can´t send mail from my mail server

Hi,

I has a Mikrotik router and my mail server can recive mails but my mail server can´t send mails. I think at my Nat setup in my mikrotik is incorrent. I has open for port 25 and 110, but i can dont sent mail. why ?

can something help me ?

thanks.

Is your mail server on the local network, or another network port?

Check that there is a SRC NAT or Masqurade for the mail server to leave the net.

Also check fire wall rules IE dont accidently block ALL port 25 traffic and forget to allow the mail server…

Baisic stuff… but OFTEN forgotten…
