SMTP issue: Dialup connection problem

A customer of mine (I know him IRL) is having problems sending emails using my SMTP server. When I do a Telnet to ANY smtp server (port 25) it connects but no data is sent from and to the server SMTP issue: Dialup connection problem He has 2 different ISP's (dialup) and I tried on both of them, doesn't work, not even with the ISP's smtp server. The server is Exim btw SMTP issue: Dialup connection problem

I tried disabling (and checking settings in) his firewall and antivirus but that doesn't help anything.

Any ideas? This is really strange... Thanks!
