I have code,
System.Web.Mail.MailMessage oMailMessage = new MailMessage();
oMailMessage.From = strFromEmaild;
oMailMessage.To = strToEmailId;
oMailMessage.Subject = strSubject;
oMailMessage.Body = strBody;
SmtpMail.SmtpServer = "localhost";
SmtpMail.Send(oMailMessage);
(all variables have values)
I have installed SMTP virtual services. why it is unable to send emails. why it is not working ??
EDIT
public bool SendMail(string strToEmailId, string strFromEmaild, string strSubject, string strBody)
{
try
{
System.Web.Mail.MailMessage oMailMessage = new MailMessage();
oMailMessage.From = strFromEmaild;
oMailMessage.To = strToEmailId;
oMailMessage.Subject = strSubject;
oMailMessage.Body = strBody;
SmtpMail.SmtpServer = "SERVERNAME";
SmtpMail.Send(oMailMessage);
return true;
}
catch (Exception ex)
{
return false;
}
}
I have this code. It is executing fine and is returning true, but I'm not getting any email in the inbox.
What else could be wrong?
Getting some mails in BadMail Dir at C:\Inetpub\mailroot\Badmail also in Queue Directory getting some mails here ... what does that means..??
I found that mail only can sent to gmail accounts... why it is?
As mentioned by others, your code is fine and is most likely something in your SMTP configuration or maybe your email client your sending your test emails to is marking them as spam. If it's spam, well that's easy enoughto figure out.
If it's something with the email, you can go to your mailroot folder and their will be some folders there with the email files along with a description. See if there's anything in the BadMail folder or the queue folder and open them up in notepad and view what error is given for why they weren't sent.
Determine what the error is:
try
{
SmtpMail.Send(oMailMessage);
}
catch (Exception ex)
{
//breakpoint here to determine what the error is:
Console.WriteLine(ex.Message);
}
From here, please edit your question with that exception details.
Its hard to tell, but one possibility is that you haven't enabled anonymous access on the SMTP virtual server. Go to the the virtual server properties dialog, select the Access tab, click the Access Control button, and make sure that Anonymous Access is enabled.
There doesn't appear to be anything functionally wrong with your program. It's likely a configuration issue between your program and the mail server. I would try the following to diagnose the problem.
Wrap the code in a try/catch block and see if the exception message contains useful data
Use 127.0.0.1 instead of localhost just to rule out anything crazy
Ensure your SMTP server is running on the standard port (25 I believe)
Hello you can follow the following code:
try
{
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;
client.Timeout = 100000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential("your gmail id", "password");
MailMessage msg = new MailMessage();
msg.To.Add(textBoxTo.Text);
msg.From = new MailAddress("your gmail id");
msg.Subject = textBoxSubject.Text;
msg.Body = textBoxMsg.Text;
Attachment data = new Attachment(textBoxAttachment.Text);
msg.Attachments.Add(data);
client.Send(msg);
MessageBox.Show("Successfully Sent Message.");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
have you tried 127.0.0.1 instead of Localhost?
Also have you tested that the SMTP service is working, check out this link for details.
In the virtual smtp server Add relay restrictions and connection control so that none of the outside connections are allowed

All,
I'm writing an application that will allow customers to submit support tickets directly from their desktop. That being said, I'd like the "FROM" email address to be their email address.
I currently have the following code:
public void SendTicketEmail()
{
try
{
string tEmail = materialListView1.SelectedItems[0].SubItems[1].Text;
string tPhone = materialListView1.SelectedItems[0].SubItems[2].Text;
string tUser = materialListView1.SelectedItems[0].Text;
MailMessage mail = new MailMessage(tEmail, "my email");
SmtpClient client = new SmtpClient();
client.Port = 25;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Host = "smtp.simplifymsp.com";
mail.Subject = "this is a test email.";
mail.Body = "this is my test email body";
client.Send(mail);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
return;
}
}
I'm assuming that my resolution at this point is to request that my hosting service enable an option where I can allow smtp outgoing emails without authentication on a specified port?
The alternative here is to have all of the support emails from each customer come from one of my preset email addresses and include a Customer ID in the subject, then create a workflow in my helpdesk ticketing system for each customer that assigns the customer's information to that ticket. That's more work than I care to do, especially when scaling.
Thank you in advance.
For what it's worth, I resolved this issue rather simply. FreshService (the website that I use for my ticketing system) reacts well with the following code:
mail.From = new MailAddress("me#me.com", "customer#customer.com");
Even though the email is coming from "me#me.com," FreshService still reads the ticket as if it came from the customer. Works beautifully.
Thank you all for your time.
I'm trying to send email from asp.net mvc controller. Gmail account used here for smpt is configured to use with less security, so that's not the problem here.
but I don't get any error message neither any exception, but it not
deliver at my expected email address.
I'm using code
var text = "email body to deliver";
SendEmail("mydeliverEmailAddress#gmail.com", text);
public static bool SendEmail(string SentTo, string Text)
{
SmtpClient client = new SmtpClient();
client.Credentials = new NetworkCredential("myemail#gmail.com", "myGmailPass");
client.Port = 465;
client.Host = "smtp.gmail.com";
client.EnableSsl = true;
try
{
MailAddress
maFrom = new MailAddress("sender_email#domain.tld", "Sender's Name", Encoding.UTF8),
maTo = new MailAddress(SentTo, "Recipient's Name", Encoding.UTF8);
MailMessage mmsg = new MailMessage(maFrom.Address, maTo.Address);
mmsg.Body = "<html><body><h1>Some HTML Text for Test as BODY</h1></body></html>";
mmsg.IsBodyHtml = true;
mmsg.Subject = "Some Other Text as Subject";
mmsg.SubjectEncoding = Encoding.UTF8;
client.Send(mmsg);
}
catch (Exception ex)
{
}
return true;
}
Wait a minute. You are using your gmail account: myemail#gmail.com and trying to send an email on behalf of sender_email#domain.tld?
For more than obvious reasons that's never gonna work. So make sure that you are using the same email address as the one you are authenticating against:
maFrom = new MailAddress("myemail#gmail.com", "Sender's Name", Encoding.UTF8),
You can only send emails from the account you are authenticated against. Of course the recipient email can be any address that gmail can deliver to.
You've got another issue with your code. You are using a wring port here:
client.Port = 465;
The correct port that gmail SMTP works with is the following:
client.Port = 587;
Also you might want to ensure that you have enabled less secure apps in your gmail account or you will not be able to use SmtpClient in .NET to send emails using this SMTP: https://www.google.com/settings/security/lesssecureapps?pli=1
but I don't get any error message neither any exception, but it not
deliver at my expected email address.
What error message do you expect to get when you did the worst ever possible thing? You wrapped your code in a try/catch block and in your catch block you did absolutely nothing. You just consumed the exception:
catch (Exception ex)
{
}
So make sure that you do something useful with an exception if you are going to be catching it. For example something useful could be to log this exception and send an error message to the user saying that something bad happened and you couldn't send an email and that you are investigating the issue right now.
var smtpClient = new SmtpClient("YourSMTPServer", "SMTPServerPort"))
{
Credentials = new NetworkCredential("YourEmail",
"Password"),
EnableSsl = false
};
string fromEmail = "YourEmail";
var mailMessage = new MailMessage();
mailMessage.From = new MailAddress(fromEmail);
mailMessage.To.Add("Recipient's EMail");
mailMessage.Subject = "Test Mail";
mailMessage.Body = "This is test Mail";
mailMessage.IsBodyHtml = true;
smtpClient.Send(mailMessage);
Following code used to work but suddenly refuses to work.
private static void SendMail()
{
try
{
var mail = new MailMessage();
var smtpServer = new SmtpClient("smtp.google.com", 587);
mail.From = new MailAddress("catthoor.jc#gmail.com", "Jasper.Kattoor");
mail.To.Add("YYYY");
mail.Subject = "sup";
mail.Body = "sup";
smtpServer.Credentials = new NetworkCredential("catthoor.jc#gmail.com", "XXXX");
smtpServer.EnableSsl = true;
smtpServer.Send(mail);
}
catch (Exception ex)
{
Console.WriteLine(ex);
Console.ReadLine();
}
}
I receive the following error:
System.Net.Mail.SmtpException: Failure sending mail. --->
System.Net.WebException: The remote name could not be resolved:
'smtp.google.com'
I've also tried using hotmail instead of gmail, same error.
I can still send mails manually though.
Why would this error suddenly occur? Yesterday there were no problems with this.
That remote host name is wrong, it should be:
smtp.gmail.com
Read all about it: Send Email from Yahoo!, GMail, Hotmail (C#)
Updates: You can also ping the host name to check if it exists using command prompt
Yes, in my case I wasn't just connected to the internet.
After I connected the problem was gone.
This code works locally, but when I upload it to my server on Godaddy, it does not send the e-mail. Any idea why it doesn't work on their server? What do I need to change?
try {
MailMessage mail = new MailMessage();
SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
mail.From = new MailAddress("Myemail#gmail.com");
mail.To.Add("Myemail#gmail.com");
mail.Subject = "New sign up";
mail.Body = "New member";
SmtpServer.Port = 587;
SmtpServer.Credentials = new System.Net.NetworkCredential("Myemail#gmail.com", "**Mypass**");
SmtpServer.EnableSsl = true;
SmtpServer.Send(mail);
} catch(Exception ex) {
throw ex;
}
They may be blocking outgoing SMTP connections in order to prevent spammers from using their service to send spam. You should check what error messages you're getting and check your server host's policy.
There are a couple of things you need to do when sending from inside a site hosted from Godaddy. Use their relay server to send the message (this won't work from your dev machine, you'll have to test it live after you upload it). Here is the relay server info. Also make sure the "from" address is an email within the same domain. I usually use the same as the toAddress. See here for info on why this is necessary.
This is the code I'm using to send from a site inside Godaddy:
btnSend.Disabled = true;
const string serverHost = "relay-hosting.secureserver.net";
var msg = new MailMessage(toAddress, toAddress);
msg.ReplyTo = new MailAddress(emailFrom);
msg.Subject = subject;
msg.Body = emailBody;
msg.IsBodyHtml = false;
try
{
var smtp = new SmtpClient();
smtp.Host = serverHost;
smtp.Credentials = new System.Net.NetworkCredential("account", "password");
smtp.Send(msg);
}
catch (Exception e)
{
//Log the errors so that we can see them somewhere
}
You need to send your email via the godaddy smtp servers. I experienced the same issue with them before I think. I believe they give instructions of how to login via their FAQ.
If you have ssh access to the server, try to telnet smtp.google.com via 25 and 465 ports also. If you get a timeout, then you're likely firewalled from connecting to these ports outside a certain IP range.
Port 587 is for TLS. As you're using SSL, try port 465.
I have used this code to send mails but I am not getting any error but I'm able to receive the mail. The default smtp server is also set to "127.0.0.1" as my local host in relay mail in the "inetmgr" but I'm still not able to receive the mail. I don't know where the problem is.
In emailsender.cs class this is the code:
public void SendEmail(string To, String Subject, String Body, String uname)
{
string body = "Hi " + uname + ",\n\n \t" + Body + "\n" + " \n Regards, \n LMS Team" + "\n\n\tSent at: " + DateTime.Now + " \n\n\t\t---- This is an auto generated mail. Please do not reply.";
try
{
try
{
MailMessage Message = new MailMessage();
Message.From = new MailAddress("karhik.varadarajan#asteor.com");
if (!string.IsNullOrEmpty(To))
Message.To.Add(new MailAddress(To));
Message.Subject = Subject;
Message.Body = body;
try
{
SmtpClient smtpClient = new SmtpClient("localhost");
smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;
smtpClient.Port = 25;
smtpClient.UseDefaultCredentials = false;
smtpClient.Send(Message);
}
catch (System.Web.HttpException ehttp)
{
throw new Exception("Email Sending Failed", ehttp);
}
}
catch (IndexOutOfRangeException ex)
{
throw new IndexOutOfRangeException("Email Sending Failed", ex);
}
}
catch (System.Exception ex)
{
throw new Exception("Email Sending Failed", ex);
}
}
In the .aspx file:
protected void Page_Load(object sender, EventArgs e)
{
EmailSender email = new EmailSender();
email.SendEmail("karhik.varadarajan#asteor.com", "testingmail", "this is a test mail", "From");
}
If you use PickupDirectoryFromIis option, Check you C:\Inetpub\mailroot\Pickup or Queue or Badmail directory whether the EML file created or not. If it is in PickUp or Queue folder, IIS may process the file. If it is in BadMail, IIS unable to process the file.
I experienced the same issue,sometimes the organization wont allow access to send email.so i tried email relaying server. try elastic email.
If there are no error there are most likely an smpt server setup problem. Firstly, you are using localhost, not 127.0.0.1. I would recommend as a best practice to use 127.0.0.1 when calling localhost.
Even if it is a "shouldn't need too" there are no reason at all, using localhost. At least put "127.0.0.1 localhost" in windows etc\hosts file. You may also try a external SMTP host that you know ou have access to (like your isp). I know misconfigured smtp hosts CAN appear as the was sended succesfully.
However, as other already stated above, there can be a lot of other problems like access to send mail. Though, i think most errors like those will throw an error back to you.
