Email not sending from the server in asp.net - c#

brief desc....
I have a application that has a few different pages, one page sends the user a new password, and another page that creates a new account and sends the user their username, password and activation link and two pdfs...
Problem... When testing locally, from the two separate pages, both are working fine and sending emails as expected.
Now when i have uploaded my application to the server, i test the same but only the new password email is sending to the user, and not the other email on the create new user page... Really strange.. i have tried the app on two different servers, again with the same outcome. only the password email sends to the user... It was working but then suddenly stopped working.. I don't understand why...
I have checked the smtp settings in iis and all is fine.. I just don't understand how it can send both email locally, but only one of the emails on the server? anybody have any incline of the issue.. ? here is my code...
private void SendActivationEmail(string password, DataTable td)
{
try

How to apped in table format using String builder

I am trying to make a table format in the body of email.
This is how I do the appending
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<table border='1' cellpadding='0' cellspacing='0'>");
sb.Append("<tr>");
sb.Append("<td>ID</td>");
sb.Append("<td>STATUS</td>");
sb.Append("</tr>");
//sb.Append("</table>");
//sb.Append(" < table border = '1' cellpadding = '0' cellspacing = '0' width = '100%' >");
foreach (var item in mylist)
{
sb.Append("<tr>");
sb.Append("<td>" + item.message + "</td>");
sb.Append("<td>" + item.transactionid + "</td>");
sb.Append("</tr>");
}
sb.Append("</table>");
var sendmail = new MailAddress("", "Akhil");
var receiver = new MailAddress("", "Buddy");
var subject = "Request for Asset!!";
var body = sb.ToString();
If you using System.Web.Mail then put messageg.BodyFormat = MailFormat.Html;
If you using System.Net.Mail then put message.IsBodyHtml = true; .
IsBodyHtml & MailFormat.Html states that your message is HTML formatted.
> This is not a true way, first you should add the HTML file, then after create a table inside the file.
Now attach a file with StringBuilder.
## Here is my send email with attachment code ##
StringBuilder sbMailBody = new StringBuilder();
sbMailBody.Append(Server.MapPath("~/Content/fielname.html"));
var sendmail = new MailAddress("", "Akhil");
var receiver = new MailAddress("", "Buddy");
var subject = "Request for Asset!!";
var body = sbMailBody.ToString();

Create HTML Table in C# with foreach loop

I want to create an HTML table with my c# program.
I've tried this:
internal string CreateMailBody(mailObj dataObj)
{
string body = string.Empty;
body +=
"Dear all, there is my new table:" +
"TableNo: " + dataObj.Obj.Table.TableNumber+ "<br /> <br />";
body += "<table border='1'><tr><th>Line No</th><th>Table</th><th>Description</th><th>Count</th><th>Met</th><th>something</th></tr>";
foreach (var item in dataObj.Table.TableLineCollection)
{
body += "<tr><td>" + item.LineNumber +"</td>";
body += "<tr><td>" + item.Table+"</td>";
body += "<tr><td>" + item.Description+"</td></tr>";
}
return body;
}
Will it give a better solution for this ?
You may mix StringBuilder using the method AppendFormat and string literals (# in from of a string, so you can write multiple lines).
StringBuilder body = new StringBuilder();
body.AppendFormat (
#"Dear all, there is my new table:
TableNo: {0} <br /> <br />
<table border='1'><tr><th>Line No</th><th>Table</th><th>Description</th><th>Count</th><th>Met</th><th>something</th></tr>"
, dataObj.Obj.Table.TableNumber);
foreach (var item in dataObj.Table.TableLineCollection)
{
body.AppendFormat(
#"<tr><td> {0}</td>
<tr><td> {1}</td>
<tr><td> {2}</td></tr>",
item.LineNumber, item.Table, item.Description);
}

How to send picture to email body in WinForms?

I have a C# Winforms application I'm working on in Visual Studio 2010, the page in question is a bug reporting form - I have all the details set, email sends fine etc. My issue is attaching a screenshot to the email in the body, I have code set up to allow users to find and select a screenshot they take and attach to the form, but in the body itself it just gives me the text "System.Windows.Forms.Picturebox", or various similarities to that if I try .image.
I've had a look around via Google and here, but can only find topics that are to do with embedding the image or attaching it (and thus require to enter in a specific folder/image etc), whereas my users will be attaching their own image and name from different places. Is there anyway to get the image to be picked up without having to hardcode a location and name that my users will have to follow each time?
Code below:
private void btnBugEmail_Click(object sender, EventArgs e)
{
Cursor.Current = Cursors.WaitCursor;
try
{
SmtpClient client = new SmtpClient("details here");
MailMessage message = new MailMessage();
message.From = new MailAddress("email here");
string mailBox = txtBugAdd.Text.Trim();
message.To.Add(mailBox);
string mailFrom = txtEmailFromBug.Text.Trim();
message.CC.Add(mailFrom);
string mailCC = txtMailCCBug.Text.Trim();
message.Bcc.Add(mailCC);
message.IsBodyHtml = true;
message.Body = "Bug Report - please see below: " +
"\n" + "<br>" + "<b>" + "1. What were you doing at the time of the error?" + "</b>" +
"\n" + "<br>" + rtbTimeOfError.Text +
"\n" + "<br>" + "<b>" + "2. Are you able to repeat the steps and achieve the same error?" + "</b>" +
"\n" + "<br>" + rtbCanRepeat.Text +
"\n" + "<br>" + "<b>" + "3. Does this problem happen again if you change any of the details you have entered?" + "</b>" +
"\n" + "<br>" + rtbChangeDetails.Text;
message.Subject = "Bug Report";
var image = pboxBugImage.Image;
using(var ms = new MemoryStream())
{
image.Save(ms, ImageFormat.Jpeg);
message.Attachments.Add(new Attachment(ms, "Screenshot.jpg"));
client.Credentials = new System.Net.NetworkCredential("credentials here");
client.Port = System.Convert.ToInt32(25);
client.Send(message);
}
new Endpage().Show();
this.Close();
}
catch
{
MessageBox.Show("my comment here");
}
}
Take a look to the following link
system.net.mail.mailmessage.attachments
You cannot put a winforms control inside the mailmessage :) it is outputted with ToString()... that is what you see in mail
Example
private void btnBugEmail_Click(object sender, EventArgs e)
{
Cursor.Current = Cursors.WaitCursor;
try
{
SmtpClient client = new SmtpClient("details here");
MailMessage message = new MailMessage();
message.From = new MailAddress("email here");
string mailBox = txtBugAdd.Text.Trim();
message.To.Add(mailBox);
string mailFrom = txtEmailFromBug.Text.Trim();
message.CC.Add(mailFrom);
string mailCC = txtMailCCBug.Text.Trim();
message.Bcc.Add(mailCC);
message.IsBodyHtml = true;
message.Body = "Bug Report - please see below: " +
"\n" + "<br>" + "<b>" + "1. What were you doing at the time of the error?" + "</b>" +
"\n" + "<br>" + rtbTimeOfError.Text +
"\n" + "<br>" + "<b>" + "2. Are you able to repeat the steps and achieve the same error?" + "</b>" +
"\n" + "<br>" + rtbCanRepeat.Text +
"\n" + "<br>" + "<b>" + "3. Does this problem happen again if you change any of the details you have entered?" + "</b>" +
"\n" + "<br>" + rtbChangeDetails.Text;
message.Subject = "Bug Report";
var image = pboxBugImage.Image;
using(var ms = new MemoryStream())
{
image.Save(ms, ImageFormat.Jpeg);
message.Attachments.Add(new Attachment(ms, "Screenshot.jpg"));
client.Credentials = new System.Net.NetworkCredential("credentials here");
client.Port = System.Convert.ToInt32(25);
client.Send(message);
}
new Endpage().Show();
this.Close();
}
catch
{
MessageBox.Show("my comment here");
}
}
Take a look at your resources and dispose the memorystream. I didnt for the example, because i wrote it here in editor

Send inline image in email

Having an issue sending an image via email as an embedded image in the body.
The image file shows as an attachment which is ok but the inline image portion just shows as a red x.
Here is what I have so far
LinkedResource inline = new LinkedResource(filePath);
inline.ContentId = Guid.NewGuid().ToString();
MailMessage mail = new MailMessage();
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
mail.Body = String.Format(
"<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
#"<img src=""cid:{0}"" />", inline.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);
Some minimal c# code to embed an image, can be:
MailMessage mailWithImg = GetMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!
private MailMessage GetMailWithImg() {
MailMessage mail = new MailMessage();
mail.IsBodyHtml = true;
mail.AlternateViews.Add(GetEmbeddedImage("c:/image.png"));
mail.From = new MailAddress("yourAddress#yourDomain");
mail.To.Add("recipient#hisDomain");
mail.Subject = "yourSubject";
return mail;
}
private AlternateView GetEmbeddedImage(String filePath) {
LinkedResource res = new LinkedResource(filePath);
res.ContentId = Guid.NewGuid().ToString();
string htmlBody = #"<img src='cid:" + res.ContentId + #"'/>";
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(res);
return alternateView;
}
Try this
string htmlBody = "<html><body><h1>Picture</h1><br><img src=\"cid:filename\"></body></html>";
AlternateView avHtml = AlternateView.CreateAlternateViewFromString
(htmlBody, null, MediaTypeNames.Text.Html);
LinkedResource inline = new LinkedResource("filename.jpg", MediaTypeNames.Image.Jpeg);
inline.ContentId = Guid.NewGuid().ToString();
avHtml.LinkedResources.Add(inline);
MailMessage mail = new MailMessage();
mail.AlternateViews.Add(avHtml);
Attachment att = new Attachment(filePath);
att.ContentDisposition.Inline = true;
mail.From = from_email;
mail.To.Add(data.email);
mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
mail.Body = String.Format(
"<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
#"<img src=""cid:{0}"" />", att.ContentId);
mail.IsBodyHtml = true;
mail.Attachments.Add(att);
protected void Page_Load(object sender, EventArgs e)
{
string Themessage = #"<html>
<body>
<table width=""100%"">
<tr>
<td style=""font-style:arial; color:maroon; font-weight:bold"">
Hi! <br>
<img src=cid:myImageID>
</td>
</tr>
</table>
</body>
</html>";
sendHtmlEmail("from#gmail.com", "tomailaccount", Themessage, "Scoutfoto", "Test HTML Email", "smtp.gmail.com", 25);
}
protected void sendHtmlEmail(string from_Email, string to_Email, string body, string from_Name, string Subject, string SMTP_IP, Int32 SMTP_Server_Port)
{
//create an instance of new mail message
MailMessage mail = new MailMessage();
//set the HTML format to true
mail.IsBodyHtml = true;
//create Alrternative HTML view
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
//Add Image
LinkedResource theEmailImage = new LinkedResource("E:\\IMG_3332.jpg");
theEmailImage.ContentId = "myImageID";
//Add the Image to the Alternate view
htmlView.LinkedResources.Add(theEmailImage);
//Add view to the Email Message
mail.AlternateViews.Add(htmlView);
//set the "from email" address and specify a friendly 'from' name
mail.From = new MailAddress(from_Email, from_Name);
//set the "to" email address
mail.To.Add(to_Email);
//set the Email subject
mail.Subject = Subject;
//set the SMTP info
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("fromEmail#gmail.com", "fromEmail password");
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;
smtp.Credentials = cred;
//send the email
smtp.Send(mail);
}
In addition to the comments above, I have the following additional comments:
Do not mix Attachments and AlternativeView, use one or the other. If you mix them, the inline attachments will be rendered as unknown downloads.
While Outlook and Google allow standard HTML-style "cid:att-001" this does NOT work on iPhone (late 2016 patch level), rather use pure alpha numeric "cid:att-001" -> "cid:att001"
As an aside: Outlook (even Office 2015) rendering (still the clear majority for business users) requires the use of TABLE TR TD style HTML, as it does not fully support the HTML box model.
An even more minimalistic example:
var linkedResource = new LinkedResource(#"C:\Image.jpg", MediaTypeNames.Image.Jpeg);
// My mail provider would not accept an email with only an image, adding hello so that the content looks less suspicious.
var htmlBody = $"hello<img src=\"cid:{linkedResource.ContentId}\"/>";
var alternateView = AlternateView.CreateAlternateViewFromString(htmlBody, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(linkedResource);
var mailMessage = new MailMessage
{
From = new MailAddress("youremail#host.com"),
To = { "recipient#host.com" },
Subject = "yourSubject",
AlternateViews = { alternateView }
};
var smtpClient = new SmtpClient();
smtpClient.Send(mailMessage);
Try This.
protected void Page_Load(object sender, EventArgs e)
{
string Themessage = #"<html>
<body>
<table width=""100%"">
<tr>
<td style=""font-style:arial; color:maroon; font-weight:bold"">
Hi! <br>
<img src=cid:myImageID>
</td>
</tr>
</table>
</body>
</html>";
sendHtmlEmail("from#gmail.com", "tomailaccount", Themessage, "Scoutfoto", "Test HTML Email", "smtp.gmail.com", 25);
}
protected void sendHtmlEmail(string from_Email, string to_Email, string body, string from_Name, string Subject, string SMTP_IP, Int32 SMTP_Server_Port)
{
//create an instance of new mail message
MailMessage mail = new MailMessage();
//set the HTML format to true
mail.IsBodyHtml = true;
//create Alrternative HTML view
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, null, "text/html");
//Add Image
LinkedResource theEmailImage = new LinkedResource("E:\\IMG_3332.jpg");
theEmailImage.ContentId = "myImageID";
//Add the Image to the Alternate view
htmlView.LinkedResources.Add(theEmailImage);
//Add view to the Email Message
mail.AlternateViews.Add(htmlView);
//set the "from email" address and specify a friendly 'from' name
mail.From = new MailAddress(from_Email, from_Name);
//set the "to" email address
mail.To.Add(to_Email);
//set the Email subject
mail.Subject = Subject;
//set the SMTP info
System.Net.NetworkCredential cred = new System.Net.NetworkCredential("fromEmail#gmail.com", "fromEmail password");
SmtpClient smtp = new SmtpClient("smtp.gmail.com", 587);
smtp.EnableSsl = true;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;
smtp.Credentials = cred;
//send the email
smtp.Send(mail);
}
The other solution is attaching the image as attachment and then referencing it html code using cid.
HTML Code:
<html>
<head>
</head>
<body>
<img width=100 height=100 id=""1"" src=""cid:Logo.jpg"">
</body>
</html>
C# Code:
EmailMessage email = new EmailMessage(service);
email.Subject = "Email with Image";
email.Body = new MessageBody(BodyType.HTML, html);
email.ToRecipients.Add("abc#xyz.com");
string file = #"C:\Users\acv\Pictures\Logo.jpg";
email.Attachments.AddFileAttachment("Logo.jpg", file);
email.Attachments[0].IsInline = true;
email.Attachments[0].ContentId = "Logo.jpg";
email.SendAndSaveCopy();
Example on how to embed multiple images into an HTML email. Note, if you try to use newer HTML elements such as flexbox you will have trouble. If you use a simple table it will work. When I tried with flexbox the styling wasn't recognized.
public static void Main(string[] args)
{
var html = File.ReadAllText("c:\test.html");
var altView = GetAlternateView(html);
SendEmail(new List<MailRecipients> {new MailAddress(someone#email.com)}, "Hello!", "Images in Email Test!", true, altView);
}
public static bool SendEmail(List<MailAddress> recipients, string body, string subject, bool html, AlternateView view, MailPriority priority = MailPriority.Normal)
{
try
{
MailMessage message = new MailMessage();
SmtpClient smtp = new SmtpClient();
message.From = new MailAddress(ConfigLookup.GetStringValue(ConfigNames.EmailFrom));
recipients.ForEach(r => message.To.Add(new MailAddress(r.Address)));
message.Subject = subject;
message.IsBodyHtml = html;
message.AlternateViews.Add(view);
message.Priority = priority;
smtp.Port = 25;
smtp.Host = youremailhost;
smtp.EnableSsl = yes;
smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Send(message);
return true;
}
catch (Exception e)
{
return false;
}
}
private AlternateView GetAlternateView(string html)
{
var logoPath = ConfigLookup.GetStringValue(ConfigNames.LogoPath);
LinkedResource logoResource = new LinkedResource(logoPath);
// ContentID must match the 'cid:contentId' in the html
logoResource.ContentId = "logo";
// Without a Mime type the images will show up as attached .bin files
logoResource.ContentType = new ContentType("image/png");
logoResource.TransferEncoding = TransferEncoding.Base64;
var heroPath = ConfigLookup.GetStringValue(ConfigNames.HeroPath);
LinkedResource heroResource = new LinkedResource(heroPath);
// ContentID must match the 'cid:contentId' in the html
heroResource.ContentId = "hero";
// Without a Mime type the images will show up as attached .bin files
heroResource.ContentType = new ContentType("image/png");
heroResource.TransferEncoding = TransferEncoding.Base64;
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(html, null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(logoResource);
alternateView.LinkedResources.Add(heroResource);
return alternateView;
}
In your Html, the main thing that links up the images to the LinkedResource is the 'cid:contentId' must match:
<a href="https://somesite.com" target="_blank" style="color:#033254;">
<img src="cid:logo" width="218" alt="Company logo" style="max-width:100%;height:auto;" />
</a>
<a href="https://somesite.com" target="_blank" style="color:#033254;">

We all have our preferred coding styles. This is what I did:
var pictures = new[]
{
new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme", path = #"C:\Pictures\JustMe.jpg" },
new { id = Guid.NewGuid(), type = "image/jpeg", tag = "justme-bw", path = #"C:\Pictures\JustMe-BW.jpg" }
}.ToList();
var content = $#"
<style type=""text/css"">
body {{ font-family: Arial; font-size: 10pt; }}
</style>
<body>
<h4>{DateTime.Now:dddd, MMMM d, yyyy h:mm:ss tt}</h4>
<p>Some pictures</p>
<div>
<p>Color Picture</p>
<img src=cid:{{justme}} />
</div>
<div>
<p>Black and White Picture</p>
<img src=cid:{{justme-bw}} />
</div>
<div>
<p>Color Picture repeated</p>
<img src=cid:{{justme}} />
</div>
</body>
";
// Update content with picture guid
pictures.ForEach(p => content = content.Replace($"{{{p.tag}}}", $"{p.id}"));
// Create Alternate View
var view = AlternateView.CreateAlternateViewFromString(content, Encoding.UTF8, MediaTypeNames.Text.Html);
// Add the resources
pictures.ForEach(p => view.LinkedResources.Add(new LinkedResource(p.path, p.type) { ContentId = p.id.ToString() }));
using (var client = new SmtpClient()) // Set properties as needed or use config file
using (MailMessage message = new MailMessage()
{
IsBodyHtml = true,
BodyEncoding = Encoding.UTF8,
Subject = "Picture Email",
SubjectEncoding = Encoding.UTF8,
})
{
message.AlternateViews.Add(view);
message.From = new MailAddress("me#me.com");
message.To.Add(new MailAddress("you#you.com"));
client.Send(message);
}
You need to add the LinkedResource into an AlternateView
AlternateView alternateView = AlternateView.CreateAlternateViewFromString("<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
#"<img src=""cid:{0}"" />", null, "text/html");
alternateView.LinkedResources.Add(inline);
mail.AlternateViews.Add(alternateView);
MailMessage mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("userid#gmail.com");
mail.To.Add("userid#gmail.com");
//set the content
mail.Subject = "Sucessfully Sent the HTML and Content of mail";
//first we create the Plain Text part
string plainText = "Non-HTML Plain Text Message for Non-HTML enable mode";
AlternateView plainView = AlternateView.CreateAlternateViewFromString(plainText, null, "text/plain");
XmlTextReader reader = new XmlTextReader(#"E:\HTMLPage.htm");
string[] address = new string[30];
string finalHtml = "";
var i = -1;
while (reader.Read())
{
if (reader.NodeType == XmlNodeType.Element)
{ // The node is an element.
if (reader.AttributeCount <= 1)
{
if (reader.Name == "img")
{
finalHtml += "<" + reader.Name;
while (reader.MoveToNextAttribute())
{
if (reader.Name == "src")
{
i++;
address[i] = reader.Value;
address[i] = address[i].Remove(0, 8);
finalHtml += " " + reader.Name + "=" + "cid:chartlogo" + i.ToString();
}
else
{
finalHtml += " " + reader.Name + "='" + reader.Value + "'";
}
}
finalHtml += ">";
}
else
{
finalHtml += "<" + reader.Name;
while (reader.MoveToNextAttribute())
{
finalHtml += " " + reader.Name + "='" + reader.Value + "'";
}
finalHtml += ">";
}
}
}
else if (reader.NodeType == XmlNodeType.Text)
{ //Display the text in each element.
finalHtml += reader.Value;
}
else if (reader.NodeType == XmlNodeType.EndElement)
{
//Display the end of the element.
finalHtml += "</" + reader.Name;
finalHtml += ">";
}
}
AlternateView htmlView = AlternateView.CreateAlternateViewFromString(finalHtml, null, "text/html");
LinkedResource[] logo = new LinkedResource[i + 1];
for (int j = 0; j <= i; j++)
{
logo[j] = new LinkedResource(address[j]);
logo[j].ContentId = "chartlogo" + j;
htmlView.LinkedResources.Add(logo[j]);
}
mail.AlternateViews.Add(plainView);
mail.AlternateViews.Add(htmlView);
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new NetworkCredential(
"userid#gmail.com", "Password");
smtp.EnableSsl = true;
Console.WriteLine();
smtp.Send(mail);
}
I added the complete code below to display images in Gmail,Thunderbird and other email clients :
MailMessage mailWithImg = getMailWithImg();
MySMTPClient.Send(mailWithImg); //* Set up your SMTPClient before!
private MailMessage getMailWithImg()
{
MailMessage mail = new MailMessage();
mail.IsBodyHtml = true;
mail.AlternateViews.Add(getEmbeddedImage("c:/image.png"));
mail.From = new MailAddress("yourAddress#yourDomain");
mail.To.Add("recipient#hisDomain");
mail.Subject = "yourSubject";
return mail;
}
private AlternateView getEmbeddedImage(String filePath)
{
// below line was corrected to include the mediatype so it displays in all
// mail clients. previous solution only displays in Gmail the inline images
LinkedResource res = new LinkedResource(filePath, MediaTypeNames.Image.Jpeg);
res.ContentId = Guid.NewGuid().ToString();
string htmlBody = #"<img src='cid:" + res.ContentId + #"'/>";
AlternateView alternateView = AlternateView.CreateAlternateViewFromString(htmlBody,
null, MediaTypeNames.Text.Html);
alternateView.LinkedResources.Add(res);
return alternateView;
}
sending 2 images vb.net code convert for C# online converter.

Unstable Sending of email in asp.net

I am building a ecommerce site and after a purchase is done, I want to send the buyer an email first before I commit my database changes but somehow, the send failure rate is about 25 - 30 percent. I am using hotmail current as a temp email account, not sure if it's hotmail's issue, anyway this is my code, any advice? Thanks:
Code:
MembershipUser u = Membership.GetUser(HttpContext.Current.User.Identity.Name);
AccountProfile usercustomProfile = new AccountProfile();
var p = usercustomProfile.GetProfile(u.UserName);
MailMessage mail = new MailMessage();
mail.To.Add(u.Email);
mail.IsBodyHtml = true;
mail.From = new MailAddress("XXX#hotmail.com");
mail.Subject = ("Purchase invoice" + ' ' + newOrder.OrderID);
string mailBodyHeader =
"<table border=0> <tr> <td>Product ID</td><td>Model Number</td><td>Model Name</td><td> Unit Cost</td> <td>Quantity</td><td>Price</td></tr>";
System.Text.StringBuilder bodyContent = new System.Text.StringBuilder();
double unitQtyPrice = 0;
double totalPrice = 0;
foreach (var cItem in cartList)
{
unitQtyPrice = cItem.Quantity * (double)cItem.UnitCost;
totalPrice += unitQtyPrice;
bodyContent.Append("<tr>");
bodyContent.Append("<td>");
bodyContent.Append(cItem.ProductID.ToString());
bodyContent.Append("</td>");
bodyContent.Append("<td>");
bodyContent.Append(cItem.ModelNumber.ToString());
bodyContent.Append("</td>");
bodyContent.Append("<td>");
bodyContent.Append(cItem.ModelName);
bodyContent.Append("</td>");
bodyContent.Append("<td>");
bodyContent.Append(Math.Round(cItem.UnitCost, 2));
bodyContent.Append("</td>");
bodyContent.Append("<td>");
bodyContent.Append(cItem.Quantity.ToString());
bodyContent.Append("</td>");
bodyContent.Append("<td>");
bodyContent.Append("$" + Math.Round(unitQtyPrice, 2));
bodyContent.Append("</td>");
bodyContent.Append("</tr>");
}
Math.Round(totalPrice, 2);
mail.Body = "Thanks you for shopping with XXX. Your purchase details are as follow:"
+ "<br><br>" + "Name:" + p.FirstName + p.LastName
+ "<br>" + "Mailing Address:" + p.MailingAddress
+ "<br>" + "Billing Address:" + p.BillingAddress

+ "<br>" + "Total Price:" + "$" + totalPrice
+ "<br>" + "Additional / Special instructions:"
+ "<br>" + SInfo
+ "<br><br>" + "Please blah blah blah";
SmtpClient client = new SmtpClient("smtp.live.com", 587);
client.EnableSsl = true; //ssl must be enabled for Gmail
NetworkCredential credentials = new NetworkCredential("XXX#hotmail.com", "ABCDE");
client.Credentials = credentials;
//Sends a message to from if email is not deliverable
mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnSuccess;
mail.DeliveryNotificationOptions = DeliveryNotificationOptions.OnFailure;
//Create the SMTPClient object and DO NOT specify the SMTP server name, it’s being pulled from config file
SmtpClient SMTPServer = new SmtpClient();
SMTPServer.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
try
{
client.Send(mail);
db.SaveChanges();
}
catch (SmtpException)
{
Server.Transfer("/CheckOutUnsuccessful.aspx", true);
}
}
return (true);
}
If you are using SQL Server on the backend you can set the database server up to handle the mail requests. The advantage of using SQL Server as opposed to ASP.NET code is the database can be configured to retry sending the messages several times on failure.
Here is a good resource on how to configure Database Mail: http://blog.sqlauthority.com/2008/08/23/sql-server-2008-configure-database-mail-send-email-from-sql-database/
