SMTP mail send problem

[Corey]

I'm running Windows/Outlook XP with mail routed through POP3/SMTP university servers. Abruptly, I am no longer able to send mail, though receiving works fine. I get an error message saying that Outlook couldn't connect with the outgoing server. No account settings have changed (I've checked) and I can still telnet to the SMTP server (but not through port 25)and send mail through a web-based university system. I do not have any Norton software on my computer, though I"m unsure about other potential firewalls. I am connecting to the internet through a cable modem which worked fine in the past.

The only change I can think of is that I recently signed up for an account and installed .NET software (MSN Messenger, .NET Framework) with my university address as my .NET login. I have since uninstalled the software and cancelled my .NET account which hasn't helped.

Any help as to what could be blocking Outlook's access to the server or port would be greatly appreciated.

Do other people have the same issue? Contact the administrator to verify
that posrt 25 isn't blocked on the server.
