Mail app not working on school wireless network?

Odds are the best way to resolve this is to contact the network administrator at your school. It's not at all uncommon for them to only allow certain programs to function or certain ports to be available.

in your mail preferences uncheck SSL

I am also having the same problem, seems that the wireless router i'm connecting with affects my mac mail's abillity to connect and receive mail, however all other internet capabilities are perfectly fine. I tried your suggestion of unchecking the "Use SSL" option and that had no affect. Any other options?

What school do you go to? They will often have information about connection instructions for these types of things.

I have been experiencing similar problems with my connection working in some locations and not in others. It seems to have something to do with what software is being used at the location to block "inappropriate use". What I'm wondering is whether it's actually a timing issue with the firewall delaying the packets or if it is the actual port being blocked. At other times, the messages have indicated that the connection timed out.

As with some of the other people on this forum, my error message is

The server error encountered was: Mail was unable to connect to server “mail.mac.com” using SSL on port 993. Verify that this server supports SSL and that your account settings are correct.

From these locations, I am able to go to the http://www.mac.com site. However, sometimes, the messages take a very long time to load or never complete loading. I don't know if this could be a connected problem. The places where I have the most problems with mail via www.mac.com are also the locations where the mail application has problems.
