mail server only sends to local

[fullback]

Hey i have a few questions,

i have set up everything correctly and all seems to be working but mail server.
I can set up mail accounts in outlook and everything goes okay but i can only send mail to domains that are in my ispconfig

for example my mail server for domain askaprofessor.org is mail.askaprofessor.org
and my e-mail for that account is
mike@askaprofessor.org
i also have another domain rabgo.com
mail for that account is test@rabgo.com
I can only send e-mails to test@rabgo.com using mike@askaprofessor.org
but if try to send a an e-mail using test@rabgo.com to bhayani1569@sbcglobal.net it will not work. Mail never gets here i tired for hours any help would be good/?? i am running centos 5.0 thank yoU!

here is the message from the log

Can you send mail to other domains apart from sbcglobal.net if you cannot then port 25 outbound is blocked, as from the logs you can not connect to the server outside.

[fullback]

fullback]hey thanks for the reply! no, i cannot send to any other domain outside of local. how can i change the port number? on postfix?

also when i go to some websites to check if my port 110, and port 25 are open they report just fine. is thier a tool i can use?? thanks

Changing the port on postfix is not the fix, You need to check with your ISP that they are not blocking port 25 outbound.

You can test by running this on your server.
telnet gmail-smtp-in.l.google.com 25
