Send email via external SMTP Server

[Guest]

I am working with three computers, my developing computer, a Web Server and a
Mail Server (Exchange).

I am trying to send a email from the Web Server via the Mail Server to a
valid email address with this code:

MailMessage msgMail = new MailMessage();
msgMail.To = "(e-mail address removed)";
msgMail.From = "(e-mail address removed)";
msgMail.Subject = "Mail Example Subject";
msgMail.Body = "MAIL EXAMPLE BODY";
SmtpMail.SmtpServer = "[Server Name]";
SmtpMail.Send(msgMail);

Which does not work.

My biggest problem is that everything works perfectly on my developing
computer when I try to send mail via the Mail Server with the same code.

Why can't I send mail from the Web Server?

System.Web.Mail use CDO. The CDO dll (cdo.dll, cdont.dll or cdoex.dll, I can't remember which one .NET use) is probably installed on you dev box, but not on the web server.

If this does not work catch the exception and check the InnerException for a more detailed message why it failed.

exception? no mail in queue? something else?

I've had trouble with SMTP and my local machine firewall - symptom was mail
sitting in the queue...
