 Posted: Tue Oct 31, 2006 9:43 pm Post subject: Postfix sent problem [SOLVED!] |
 |
|
I have setup Postfix as mailserver and can sent mail to a friend of me, who has also Postfix as mailserver running.
Log says; relay=adres[xxx.xxx.xxx.xxx], delay=1, status=sent (250 Ok: queued as 0006A35A59A)
But i can't sent mail to other other mailservers eg. hotmail, friends and my ISP mailaccounts.
Logging says; relay=none, delay=0, status=deferred (connect to Some_name_of_mailserver[xxx.xxx.xxx.xxx]: Connection refused)
I'm behind a speedtouch 510 and NAPT some ports to the mailserver, but even in DMZ sending is not working accept to Postfixserver of my friend.
What am i missing here? Are others checking on something?
Anyone has an idea?
Thanx in advance.
Regards,
Ray

can you connect via telnet (port 25) on your box to those machines?
Port 25 TCP internal -> outside should be allowed to send to other mailservers |

| Only a telnet session on port 25 to my friends mailserver. Not to the others on port 25, i get "unable to connect to remote host: Connection refused." or a "Timed out". As if they are not making use of port 25. What could cause this problem? |

No there are no restrictions from my ISP (XS4ALL). It says even to have port 25 open. |

They seem to work just fine. do you try to connect via ip or hostname? maybe the dns resolution isn´t working correctly |

I **KISS** you man!! Thank you realy very much!
Have been breaking my head on this one, a whole week and what was this problem......DNS!
Just a stupid DNS issue here. I got in my resolv.conf this:
nameserver 10.0.0.38
nameserver <dns.myprovider.1>
nameserver <dns.myprovider.2>
And this nameserver 10.0.0.138 was the problem. I removed it and working!
Again, problems have such an easy solution most of the time 
Thanks!
Best regards,
Ray |
