I tried to use Microsoft Outlook Express to connect to my ISP from work and
this is the error message I got:

The connection to the server has failed. Account:
'postoffice.worldnet.att.net', Server: 'postoffice.worldnet.att.net',
Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10060, Error
Number: 0x800CCC0E

I also tried to telnet to the mail server from work but it couldnt open a
connection either.
So I guess this is a firewall issue.

Excuse my networking ignorance but I'm curious: how does Yahoo Messenger
work on my PC at work?  That needs to connect externally too.

Thanks.

I tried to telnet to the ISP's mail server on port 110 but
