Mail can't send Mail

[ribbonthecat]

This afternoon I set up a new Wi-Fi router, with AT&T Yahoo DSL, and with an Airport Express as the router. Now, whenever I try to send an email through my university's STMP server, I get a message that Mail cannot send the email through the server. When I connect to a different Wi-Fi network, Mail can then send the email without any problems. Can anybody diagnose the problem and propose a remedy?

You're more then likely not using proper ports or encryption.

So how do I fix that? What is a port? The network is encrypted with a 40-bit WEP.

I'd check your university's knowledge base for the correct port. It's more then like port 587.

Encryption would be for your authentication.

Not sure if its just a settings issue but if they are correct also check with AT&T.

When I used to have DSL I could not send e-mail out via any other SMTP server other than yahoo's. I had to use webmail for my domain e-mail for awhile.

I dont know if this is still the case/I heard from a friend that it's available with DSL Pro package but I dont know if thats true or not.
