Postfix & Spamassassin Port Change

I can connect fine to mail.charter.net:

Code:

telnet mail.charter.net 25
Trying 209.225.8.224...
Connected to mail.charter.net.
Escape character is '^]'.
220 charter.net ESMTP
ehlo localhost
250-charter.net
250-8BITMIME
250 SIZE 15728640
quit
221 charter.net
Connection closed by foreign host.

Is your server hosted on a dynamic IP address or blacklisted? I think that mail.charter.net is blocking you therefore. Maybe you should try relaying through another mail server: http://www.howtoforge.com/forums/showthread.php?t=72&highlight=relayhost

 

yes i have a dynamic ip but it never changes. This server is at work. The charter.net address is where it was trying to connect to send a test message not relaying through it. It must be a problem with the install or the change in postfix to an alternate port.

I built a vmware image to run from home for xg3d.net following your tutorial and it works without any problem. The only thing different between the one at work and one at home is that my home isp does not block port 25

 

So at work port 25 is blocked? Then it cannot work...

 

so then the port 25 cannot be changed somewhere to make it work
