Mail.app error 13 Permission denied

[StepS]

Help!
In mail, I am not able to get/send mail from one of my pop account. I have always the message: unable to connect to mail server on port 110 error 13 permission denied.
I have done a repair of authorisations, tried to configure a new mail account no changes. I can access my mailbox trough the web without problems. My other pop accounts work perfectly using the port 110. The helpdesk does not understand...
It seems that it happened after configuring the network in Parallels Desktop (windows XP).
Any suggestions?
Thanks

Have you tried using a different application to access the same pop account? Sounds to me like it may be a server side issue. Try temporarily using a different mail client like Thunderbird or Opera. If that doesn't work either then its a server side issue and not Mail.app.

Thanks for advice. I did try with entourage, same thing. The IT people worked about 2 hours to understand. Apparently the port 110 was corrupted only in mail and for a specific account. No package could go through. They couldn't fix it. They believe it's when I enabled the network in Parallels (which create a new network port (en2..something) that it happened. I reinstalled the system, and all is working perfectly now!
