So I've been pounding on this for a little bit now and I can't seem to figure out how to take a photo captured from a webcam and attach it to an email. Both send the email successfully with an image attached. However, when I try to open the image, it won't open.
First I tried using LightBuzz.SMTP
private async Task<SmtpResult> SendAlertEmail(List<CapturedPhoto> images)
{
using (SmtpClient client = new SmtpClient("smtp.gmail.com", 465, true, "mygmail#gmail.com", "myPassword"))
{
EmailMessage emailMessage = new EmailMessage();
emailMessage.Sender.Address = "IoTAlertApp#donotreply.com";
emailMessage.Sender.Name = "IoT App";
emailMessage.To.Add(new EmailRecipient("myemail#gmail.com"));
emailMessage.Subject = "ALERT | MOTION DETECTED";
emailMessage.Body = "This is an email sent from a UWP app!";
foreach (CapturedPhoto image in images)
{
int imageCount = 1;
string fileName = "image_" + imageCount + "_" + DateTime.Now.Ticks + ".jpg";
RandomAccessStreamReference reference = RandomAccessStreamReference.CreateFromStream(image.Frame.CloneStream());
emailMessage.Attachments.Add(new EmailAttachment(fileName, reference));
break;
}
images.Clear();
SmtpResult result = await client.SendMailAsync(emailMessage);
return result;
}
}
Then I tried using EASendMailRT and got the same result
private async Task Send_Email(byte[] image)
{
String Result = "";
try
{
SmtpMail oMail = new SmtpMail("TryIt");
SmtpClient oSmtp = new SmtpClient();
oMail.From = new MailAddress("IoTSquatter#DoNotReply.com");
oMail.To.Add(new MailAddress("myemail#gmail.com"));
oMail.Subject = "ALERT | MOTION DETECTED";
SmtpServer oServer = new SmtpServer("smtp.gmail.com");
oServer.User = "myemail#gmail.com";
oServer.Password = "password";
oServer.Port = 465;
oServer.ConnectType = SmtpConnectType.ConnectSSLAuto;
Attachment oAttachment = oMail.AddAttachment("testImage.jpg",image);
string contentID = "test001#host";
oAttachment.ContentID = contentID;
oMail.HtmlBody = "<html><body>this is an <img src=\"cid:"
+ contentID + "\"> embedded picture.</body></html>";
await oSmtp.SendMailAsync(oServer, oMail);
Result = "Email was sent successfully!";
}
catch (Exception ep)
{
Result = String.Format("Failed to send email with the following error: {0}", ep.Message);
}
}
I'm not sure what I'm doing wrong. I think it has to do with the file format.
The answer ended up being the way I was creating the stream. Below is the proper stream to hand off to the email.
var stream = new InMemoryRandomAccessStream();
await mediaCapture.CapturePhotoToStreamAsync(ImageEncodingProperties.CreateJpeg(), stream);
Then I added it like this
string fileName = "image_"+imageCount+".png";
RandomAccessStreamReference reference = RandomAccessStreamReference.CreateFromStream(stream);
emailMessage.Attachments.Add(new EmailAttachment(fileName, reference));
Here's the result from LightBuzz
using System.Net.Mail;
protected void SendMail()
{
try
{
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.google.com");
SmtpServer.Timeout = 30000;
SmtpServer.DeliveryMethod = SmtpDeliveryMethod.Network;
mail.From = new MailAddress("myemail#gmail.com");
mail.To.Add("recipient#gmail.com");
mail.Subject = "test";
mail.Body = "test";
mail.Priority = MailPriority.High;
SmtpServer.Port = 587;//25
SmtpServer.Credentials = new System.Net.NetworkCredential("myemail#gmail.com", "pwd");
SmtpServer.EnableSsl = true;
SmtpServer.UseDefaultCredentials = false;
SmtpServer.Send(mail);
//MessageBox.Show("mail Send");
}
catch (Exception ex)
{
//MessageBox.Show(ex.Message.ToString());
}
}
I have not found any error in my code as per several sources on internet. Still this is not working out.
Change you gmail Account Access
Sign in with your Google Account and redirect to this link
https://www.google.com/settings/security/lesssecureapps
Press the Enable, and try your code again
https://support.google.com/accounts/answer/6010255
Try this method
In Gmail Use Port-25 and SMTP-smtp.gmail.com
public void mail(string FromEmail, string FromPass, string To, string Tocc, string Tobcc, string subject, string message, string smtpadd, int portnum)
{
try
{
System.Net.Mail.SmtpClient st = new System.Net.Mail.SmtpClient(smtpadd);
System.Net.Mail.MailMessage mst = new System.Net.Mail.MailMessage();
mst.To.Add(To);
if (Tocc != "")
{
mst.CC.Add(Tocc);
}
if (Tobcc != "")
{
mst.Bcc.Add(Tobcc);
}
mst.IsBodyHtml = true;
mst.From = new System.Net.Mail.MailAddress(FromEmail);
mst.Subject = subject;
mst.Body = message;
System.Net.NetworkCredential nc = new System.Net.NetworkCredential(FromEmail, FromPass);
st.UseDefaultCredentials = true;
st.EnableSsl = true;
st.Port = portnum;
st.Credentials = nc;
st.Send(mst);
}
catch (Exception e)

}
I'm very new to the ASP.NET C# area. I'm planning to send a mail through ASP.NET C# and this is the SMTP address from my ISP:
smtp-proxy.tm.net.my
Below is what I tried to do, but failed.
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="SendMail" %>
<html>
<head id="Head1" runat="server"><title>Email Test Page</title></head>
<body>
<form id="form1" runat="server">
Message to: <asp:TextBox ID="txtTo" runat="server" /><br>
Message from: <asp:TextBox ID="txtFrom" runat="server" /><br>
Subject: <asp:TextBox ID="txtSubject" runat="server" /><br>
Message Body:<br>
<asp:TextBox ID="txtBody" runat="server" Height="171px" TextMode="MultiLine" Width="270px" /><br>
<asp:Button ID="Btn_SendMail" runat="server" onclick="Btn_SendMail_Click" Text="Send Email" /><br>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</form>
</body>
</html>
And below is my code-behind:
using System;
using System.Web.UI.WebControls;
using System.Net.Mail;
public partial class SendMail : System.Web.UI.Page
{
protected void Btn_SendMail_Click(object sender, EventArgs e)
{
MailMessage mailObj = new MailMessage(
txtFrom.Text, txtTo.Text, txtSubject.Text, txtBody.Text);
SmtpClient SMTPServer = new SmtpClient("127.0.0.1");
try
{
SMTPServer.Send(mailObj);
}
catch (Exception ex)
{
Label1.Text = ex.ToString();
}
}
}
PS: I'm sorry that I couldn't understand the receiver/sender SMTP concept, and so I am trying to understand the whole concept from here.
Just go through the below code.
SmtpClient smtpClient = new SmtpClient("mail.MyWebsiteDomainName.com", 25);
smtpClient.Credentials = new System.Net.NetworkCredential("info#MyWebsiteDomainName.com", "myIDPassword");
// smtpClient.UseDefaultCredentials = true; // uncomment if you don't want to use the network credentials
smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
smtpClient.EnableSsl = true;
MailMessage mail = new MailMessage();
//Setting From , To and CC
mail.From = new MailAddress("info#MyWebsiteDomainName", "MyWeb Site");
mail.To.Add(new MailAddress("info#MyWebsiteDomainName"));
mail.CC.Add(new MailAddress("MyEmailID#gmail.com"));
smtpClient.Send(mail);
Try using this code instead. Note: In the "from address" give your correct email id and password.
protected void btn_send_Click(object sender, EventArgs e)
{
System.Net.Mail.MailMessage mail = new System.Net.Mail.MailMessage();
mail.To.Add("to gmail address");
mail.From = new MailAddress("from gmail address", "Email head", System.Text.Encoding.UTF8);
mail.Subject = "This mail is send from asp.net application";
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.Body = "This is Email Body Text";
mail.BodyEncoding = System.Text.Encoding.UTF8;
mail.IsBodyHtml = true;
mail.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
client.Credentials = new System.Net.NetworkCredential("from gmail address", "your gmail account password");
client.Port = 587;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try
{
client.Send(mail);
Page.RegisterStartupScript("UserMsg", "<script>alert('Successfully Send...');if(alert){ window.location='SendMail.aspx';}</script>");
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
}
Page.RegisterStartupScript("UserMsg", "<script>alert('Sending Failed...');if(alert){ window.location='SendMail.aspx';}</script>");
}
}
You can try this using hotmail like this:-
MailMessage o = new MailMessage("From", "To","Subject", "Body");
NetworkCredential netCred= new NetworkCredential("Sender Email","Sender Password");
SmtpClient smtpobj= new SmtpClient("smtp.live.com", 587);
smtpobj.EnableSsl = true;
smtpobj.Credentials = netCred;
smtpobj.Send(o);
Try the following :
try
{
var fromEmailAddress = ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();
string body = "Your registration has been done successfully. Thank you.";
MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
message.Subject = "Thank You For Your Registration";
message.IsBodyHtml = true;
message.Body = body;
var client = new SmtpClient();
client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
client.Host = smtpHost;
client.EnableSsl = true;
client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
client.Send(message);
}
catch (Exception ex)
{
throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}
And then in you web.config add the following in between
<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>
You can try MailKit
MailKit is an Open Source cross-platform .NET mail-client library that is based on MimeKit and optimized for mobile devices. You can use easily in your application.You can download from here.
MimeMessage mailMessage = new MimeMessage();
mailMessage.From.Add(new MailboxAddress(fromName, from#address.com));
mailMessage.Sender = new MailboxAddress(senderName, sender#address.com);
mailMessage.To.Add(new MailboxAddress(emailid, emailid));
mailMessage.Subject = subject;
mailMessage.ReplyTo.Add(new MailboxAddress(replyToAddress));
mailMessage.Subject = subject;
var builder = new BodyBuilder();
builder.TextBody = "Hello There";
try
{
using (var smtpClient = new SmtpClient())
{
smtpClient.Connect("HostName", "Port", MailKit.Security.SecureSocketOptions.None);
smtpClient.Authenticate("user#name.com", "password");
smtpClient.Send(mailMessage);
Console.WriteLine("Success");
}
}
catch (SmtpCommandException ex)
{
Console.WriteLine(ex.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}

if your using go daddy server this work . add this in web.config
<appSettings>
---other ---setting
<add key="FromEmailAddress" value="myemail#gmail.com" />
<add key="FromEmailDisplayName" value="anyname" />
<add key="FromEmailPassword" value="mypassword#" />
<add key="SMTPHost" value="relay-hosting.secureserver.net" />
<add key="SMTPPort" value="25" />
</appSettings>
if you are using localhost or vps server change this configuration to this
<appSettings>
---other ---setting
<add key="FromEmailAddress" value="myemail#gmail.com" />
<add key="FromEmailDisplayName" value="anyname" />
<add key="FromEmailPassword" value="mypassword#" />
<add key="SMTPHost" value="smtp.gmail.com" />
<add key="SMTPPort" value="587" />
</appSettings>
change the code
client.EnableSsl = true;
if your are using gmail please enable secure app. using this link
https://myaccount.google.com/lesssecureapps?pli=1&rapt=AEjHL4Pd6h3XxE663Flvd-FfeRXxW_eNrIsGTBlZklgkAHZEeuHvheCQuZ1-djB9uIWaB-2EV7hyLCU0dWKA7D0JzYKe4ZRkuA
If you want to generate your email bodies in razor, you can use Mailzory. Also, you can download the nuget package from here.
// template path
var viewPath = Path.Combine("Views/Emails", "hello.cshtml");
// read the content of template and pass it to the Email constructor
var template = File.ReadAllText(viewPath);
var email = new Email(template);
// set ViewBag properties
email.ViewBag.Name = "Johnny";
email.ViewBag.Content = "Mailzory Is Funny";
// send email
var task = email.SendAsync("mailzory#outlook.com", "subject");
task.Wait()
According to this :
SmtpClient and its network of types are poorly designed, we strongly
recommend you use https://github.com/jstedfast/MailKit and
https://github.com/jstedfast/MimeKit instead.
Reference : https://learn.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "joey#friends.com"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "chandler#friends.com"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = #"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);

Google may block sign-in attempts from some apps or devices that do not use modern security standards. Since these apps and devices are easier to break into, blocking them helps keep your account safer.
Some examples of apps that do not support the latest security standards include:
The Mail app on your iPhone or iPad with iOS 6 or below
The Mail app on your Windows phone preceding the 8.1 release
Some Desktop mail clients like Microsoft Outlook and Mozilla Thunderbird
Therefore, you have to enable Less Secure Sign-In (or Less secure app access) in your google account.
After sign into a google account, go to:
https://www.google.com/settings/security/lesssecureapps
or
https://myaccount.google.com/lesssecureapps
In C#, you can use the following code:
MimeMessage message = new MimeMessage();
BodyBuilder Attachmint = new BodyBuilder();
message.From.Add(new MailboxAddress("name sender", "Mail From"));
message.To.Add(MailboxAddress.Parse("Mail To"));
message.Subject = Subject;
message.Body = new TextPart("plain")
{
Text = tex_body.Text + Massage
};
Attachmint.Attachments.Add("Attatchment Path");
message.Body = Attachmint.ToMessageBody();
SmtpClient client = new SmtpClient();
client.Connect("smtp.gmail.com", 465, true);
client.Authenticate("Mail from", "Password mail");
client.Send(message);
you can send mail from Gmail to Private Mail As X#PrivetCompany.com

This is the easiest script to test.
<%# Import Namespace="System.Net" %>
<%# Import Namespace="System.Net.Mail" %>
<script language="C#" runat="server">
protected void Page_Load(object sender, EventArgs e)
{
//create the mail message
MailMessage mail = new MailMessage();
//set the addresses
mail.From = new MailAddress("From email account");
mail.To.Add("To email account");
//set the content
mail.Subject = "This is a test email from C# script";
mail.Body = "This is a test email from C# script";
//send the message
SmtpClient smtp = new SmtpClient("mail.domainname.com");
NetworkCredential Credentials = new NetworkCredential("to email account", "Password");
smtp.Credentials = Credentials;
smtp.Send(mail);
lblMessage.Text = "Mail Sent";

I try two application, one in java and one in C#. The java application can send email successfully but the C# cannot. Here is the two apps :
1.Java
final String username = "myaccount#mydomain";
final String password = "mypassword";
String smtpHost = "smtp.mydomain";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.host", smtpHost);
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
Session session = Session.getDefaultInstance(props, new javax.mail.Authenticator() {
#Override
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(username));
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(username));
message.setSubject("Test send email");
message.setText("Hi you!");
Transport.send(message);
2.C#
string username = "myaccount#mydomain";
string password = "mypassword";
string smtpHost = "smtp.mydomain";
SmtpClient mailClient = new SmtpClient(smtpHost, 465);
mailClient.Host = smtpHost;
mailClient.Credentials = new NetworkCredential(username, password);
mailClient.EnableSsl = true;
MailMessage message = new MailMessage(username, username, "test send email", "hi u");
mailClient.Send(message);
So, what is the mistake i made in C# application? Why it cannot send email?
EDIT:
I have read this question How can I send emails through SSL SMTP with the .NET Framework? and it works. The deprecated System.Web.Mail.SmtpMail works but System.Net.Mail.SmtpClient doesn't. Why ?
3.This C# code work fine :
System.Web.Mail.MailMessage myMail = new System.Web.Mail.MailMessage();
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver","smtp.mydomain");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport","465");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing","2");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", "myaccount#mydomain");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", "mypassword");
myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true");
myMail.From = "myaccount#mydomain";
myMail.To = "myaccount#mydomain";
myMail.Subject = "new code";
myMail.BodyFormat = System.Web.Mail.MailFormat.Html;
myMail.Body = "new body";
System.Web.Mail.SmtpMail.SmtpServer = "smtp.mydomain:465";
System.Web.Mail.SmtpMail.Send(myMail);
The .NET System.Net.Mail.SmtpClient class cannot handle implicit SSL connection. Implicit SSL connections are sent over Port 465, as the client is configured in your example.
You can use a third party library like AIM (Aegis Implicit Mail) to send implicit SSL messages.
You can try this code as well. Also sends the email in a seperate thread.
using System.Net.Mail;
public static void Email(string Content, string To, string Subject, List<string> Attach = null, string User = "sender#sender.com", string Password = "MyPassword", string Host = "mail.sender.com", ushort Port = 587, bool SSL = false)
{
var Task = new System.Threading.Tasks.Task(() =>
{
try
{
MailMessage Mail = new MailMessage();
Mail.From = new MailAddress(User);
Mail.To.Add(To);
Mail.Subject = Subject;
Mail.Body = Content;
if (null != Attach) Attach.ForEach(x => Mail.Attachments.Add(new System.Net.Mail.Attachment(x)));
SmtpClient Server = new SmtpClient(Host);
Server.Port = Port;
Server.Credentials = new System.Net.NetworkCredential(User, Password);
Server.EnableSsl = SSL;
Server.Send(Mail);
}
catch (Exception e)
{
MessageBox.Show("Email send failed.");
}
});
Task.Start();
}
