Problems after changed server hostname/IP

[GuS]

Hi guys, after installing all the server including ISPCP, i've decided to change the hosname and also the IP in everywhere needed (also taking in mine what the wiki says here).
The old hostname of the server was distal-mx.distalnet.com and the new one is mail.distalnet.com. In everywhere in postfix exist the new hostname configured, also in bind (DNS), ispcp, etc etc etc.

Still, i have this problem:

...
(repeated some times)

I use an email account called spam@distalnet.com to store all SPAM emails there (which i've configured amavis to do the job). The account obviously exist. Also the spam mails is sent to that account. But sometimes during the day it happens what that logs says (and the last part get repeated many times).
Any tip where else must be this old hostname located?

Thanks.
