Cant receive External email

[levin]

Dear all,

I followed "The Perfect Server - CentOS 5.3 x86_64" (http://www.howtoforge.com/perfect-server-centos-5.3-x86_64-ispconfig-3)

Everythings work perfect, except that I cant receive email from external.

when trying to send email from Gmail to mydomain email, I got:

The error that the other server returned was: 550 550 #5.1.0 Address rejected xxx@mydomain.com

As I disabled the firewall, ports shall not be blocked.

Any hints :)
or where to look for the error for email receiving.

Thanks
Levin
