Mail.app broken?

[defarrow]

I recently upgraded from dial-up at home to broadband (with iPrimus in Australia). I ran a program called iConnect supplied by iPrimus. It all
went (relatively) smoothly, the speed-up is great etc.

However, all my (and my wife's) e-mail accounts under Mac Mail no
longer work. We can neither send nor recieve mail using Mail.

Things I've tried:
* Deleted and reinstalled accounts
* rebuild mailboxes (as suggested by someone)
* moved comp.apple.mail.plist out of ~/Library
* rebooted the Mac and modem.
None of these made any difference. Running Connection Doctor within
Mail just says it cannot connect to either the pop or smtp servers for
any of my mail accounts (including a .mac account).

I have successfully accessed my mail using Firefox and Entourage so
it looks like there is a problem with Mail.

I'm at a loss as to what to try next. Is there a way to re-install Mail?

I've sent an e-mail to iPrimus support but I reckon I might as well have
sent a letter to the north pole.

Any suggestions about how to fix this problem would be gratefully recieved!

O.K. The first thing you have to know most modern ISPs block port 25 outside of their own email servers. So for a .Mac account the SMTP port should be changed to port 587 to use Apple's send email servers. for apple's recieve "pop" email you have to check your local (Apple Australia) .Mac help page and check what the receive port, setup should be. Good Luck.
