It seems they have also banned outside access to their POP3 server.  I 
get the same result when I 'telnet mail.attbi.com 110' from work. 
Fetchmail is now broken.  Darn.  It seems unreasonable that one would 
be expected to download mail exclusively from home.

Port 25 (smtp) being closed to the outside, OTOH, seems reasonable (if 
a bit unorthodox).  The only reason you would need connectivity to this 
port is for relay, which SHOULD be closed to outside networks anyhow. 
You should probably use the relay provided by your dial-up ISP.
