SMTP Exception: Failure sending mail. Unable to connect to the remote server

Hey all,

I keep getting an exception when I try to send an automated email message in an asp.net 2.0 application:

I think that I have the SMTP object code and MailMessage code set up correctly...I read somewhere that I should check the firewall settings or anti-virus settings. I don't remember having this much trouble with simple web mail before though!

Thanks in advance.

well..

turns out that they have all of the smtp stuff turned off here..

that's the problem

Was about to say it seems to be a mail server problem. If you are testing this from your local machine you may be able to use localhost as a mail server as a temporary solution. I know that's what I did when my school wouldn't let me relay mail through their server for a project. Worked fine for me :)

GREAT...

thanks.
