Cannot check mail with mail application

Question

I keep trying to check my mail, but it gives me this error:
There may be a problem with the mail server or network. Check the settings for account ".Mac Account" or try again.
The server error encountered was: The connection to the server "mail.mac.com" on port 993 timed out.
My password is correct and I can check my mail from the wireless connection at the cafe down the road. I am thinking it has to do with my connection to the internet in my student housing. I am using a dial-up connection with which I have to change the proxy settings in the network preferences. I had to change my proxies to get my iChat to work, but I cannot find where to change them for the Mail application.
Again, it could be a different problem.

Answer 1

It sounds like a proxy issue. My guess is the on-campus proxy server does not use port 993 for mail. You'll either have to contact you computer help desk to find out what the correct port is, or see if the info is available online line at your university's help site. The campuses I've worked at locked down certain ports to try and keep viruses, trojans, etc., from getting into the system. Whereas Internet cafes usually leave everything open and let the user deal with any problems that occur.
