Change ports used by mail?

Hello, I run ISPConfig 2.2.13 on Debian Sarge 4.0 here at home to test websites before I put them online. My ISP (Bellsouth) blocks port 25 so that having mail doesn't work (they do this to keep you from running mail ie: spam servers). Is there any way to have Postfix use a different port? I really need the email ability because the things I'm developing send out log files via email. Any help is appreciated. Thx

Do is use this line verbatim?:

Code:

587 inet n - - - - smtpd

 

Yes, you must add/enable that line in /etc/postfix/master.cf and restart Postfix.
