Poczta po zmianie na lokalną maszyne

[ares-x]

Witam
Mam pytanie odnośnie postfixa lub sendmaila.

Niedawno działał na zew. ip z nazwą domenową i wszystko ok
A jak został przepięty za router D-linka  to po konfiguracji możemy wysyłać e-maila na konta na serwerze a na zewnątrz nie da rady. Od innych np. o2.pl tez przychodzi.
A znowu postfix wysyłał ale nie obierał. masakra

dnl This is the sendmail macro config file. If you make changes to this file,
dnl you need the sendmail-cf rpm installed and then have to generate a
dnl new /etc/sendmail.cf by running the following command:
dnl
dnl        m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
dnl
include(`/usr/share/sendmail-cf/m4/cf.m4')
