Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

So I've managed to setup bind9 and a mail server, but it seems there is something wrong. I don't quite under stand this error:

The configuration of your mail servers and your DNS are not ok! The report of the test is: 
mail.aplision.com. -> mail.aplision.com -> 208.xxx.xxx.xxx -> lisa.aplision.com
Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server.

Can anyone explain this to me in a bit more detail, and maybe point me in a direction to solve this?

The system is complaining because the IP address of your mail server has a PTR record which refers to a hostname (lisa.aplision.com) which does not itself exist.

Simply add:

lisa IN A 208.77.101.5

to your zone file and all should be well.
