Sending SMTP Email across domains

[jethro]

When sending email I get a Delivery Status Notification (Failure) for any recipients outside my domain. My code is as follows:

 

Const cdoSendUsingMethod As String = "http://scemas.microsoft.com/cdo/configuration/sendusing"

Const cdoSMTPServer As String = "http://schemas.microsoft.com/cdo/configuration/smtpserver"

Const cdoSMTPServerPort As String = "http://schemas.microsoft.com/cdo/configuration/smtpserverport"

 

 

EmailList = db.RetrieveRow(sql)

 

EmailSendTo = EmailList(0)

'EmailSendTo = "mylist@mylist.com"

EmailSubject = ReportName & " Report for " & Date.Now.ToShortDateString

 

EmailBody = EmailList(1) & " " & Date.Now.ToShortDateString & ". Please contact me if you have questions or concerns."

 

 

Try

objMessage = CreateObject("CDO.Message")

With objMessage.Configuration

.Fields(cdoSendUsingMethod) = cdoSendUsingPort

.Fields(cdoSMTPServer) = "smtp.comcast.net"

.Fields(cdoSMTPServerPort) = 25

.Fields.Update()

End With

With objMessage

.MimeFormatted = True

'.

.From = gFrom

.To = EmailSendTo

.Subject = EmailSubject

.TextBody = EmailBody

.AddAttachment(ReportPath)

.Send()

End With

 

 

Catch ex As Exception

 

End Try

 

objMessage = Nothing

IIRC you will need to configure the SMTP service (via Internet Information Services Manager) to relay mail to other domains.

Function to send mail

 

IIRC you will need to configure the SMTP service (via Internet Information Services Manager) to relay mail to other domains.

This is a function that I used to send mail from an account that require auth.

 

public bool SendMail( string CONTENT)
{
  try
  {
	string bcc = "";
	string to = "yourmail@mail.com";
	string from = "yourmail@mail.com";
	string subj = "SOME SUBJECT";
	string username = "USER";
	string password = "PASSWORD";		

	MailMessage msg = new MailMessage();

	msg.Bcc = bcc;

	msg.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserver"] = "smtp.yourserver.com";
	msg.Fields["http://schemas.microsoft.com/cdo/configuration/smtpserverport"] = 25;
	msg.Fields["http://schemas.microsoft.com/cdo/configuration/sendusername"] = username;
	msg.Fields["http://schemas.microsoft.com/cdo/configuration/sendpassword"] = password;
	msg.Fields["http://schemas.microsoft.com/cdo/configuration/smtpauthenticate"] = "1";
		  
	msg.To = to;
	msg.From = from;
	msg.Subject = subj;
	msg.Body = CONTENT;

	// Here you can set if you want HTML format or plain text
	msg.BodyFormat = MailFormat.Html;
	SmtpMail.SmtpServer = m_Serveur;
	SmtpMail.Send(msg);
	msg = null;
	return true;
  }

  catch( Exception e)
  {
	Console.WriteLine( e.Message);
	return false;
  }
}

 

You'll only need System.Web.Mail.

So have fun !
