MY postfix does not show that it is listening to the smtp daemon getting mesaage below:

The message WAS NOT relayed Reporting-MTA: dns; mail.mak.ac.ug Received-From-MTA: smtp; mail.mak.ac.ug ([]) Arrival-Date: Wed, 19 May 2010 12:45:20 +0300 (EAT)

Your postfix is it the final hop for muklists.mak.ac.ug ? Check your DNS entries for this domain. Is there an error ?

I think postfix say "Hey it's not for me, I send to muklists.mak.ac.ug. Who is muklists.mak.ac.ug ? say DNS or /etc/hosts. Then it is send to, which say Hey it's not for me"

You can maybe check your logs too : you should see a large loop, because hopcount_limit is 50 by default

  • Double check MX record of mail.mak.ac.ug. you have to do it within linux box terminal & a third party dns resolver like intodns.com or checkdns.net intodns.com/mak.ac.ug – risyasin May 20 '10 at 19:23
