Was trying to setup postfix on my home PC. Running CentOS 6.4. I don’t have a static IP and use zoneedit and ddclient to keep my installation of zoneminder current.
So I decided I wanted to get zoneminder to send me email alerts. Sent some test messages but none were sent.
I went to webdnstools website thinking maybe there is a dns or network problem.
When it checks my dns setup, everything is fine except the mail server is has the wrong IP address. The A record and the www A record have the correct IP. The IP address its reporting is one that belongs to my ISP.
