Default postfix trouble with newsletter sending

hi there.

a friend of mine is hosted by a pretty bad service provider and now they couldn't handle his email for more than a week, so I proposed to host his email till he sorts this problem out.

what I did basically was change his DNS entries so that mail.quilombobrasil.com points to my IP and added an MX record for knightsenglish.com pointing towards mail.knightsenglish.com

this works all eprfect his emails started coming onto my server, sending/receiving works perfectly.

BUT now comes the problem. On his .asp website, done years ago by somebody who is no longer available, runs a newsletter whose settigns I can't figure out as I have no idea about ASP.
whenever he sends out his newsletter, my server goes completely crazy and I get all these emails with the following content:

It seems as if the other server can't look up knightsenglish.com. Maybe that server is using nameservers that are out of date...

hmmm.... thats weird, as the newsletter .asp script runs untouched on the original server, all that changed was that the MX is different now....

Must check the DNS stuff on that server, maybe it references itsself as the MX !?

now just came another "late" report, from the server I moved the MX to:

I'm not sure what that means:

Are there any errors in the mail log?

:-( the mailbox was full
the custom filter I had set to delete all incoming messages was not working.

Incoming email was supposed to get an autoresponder and then be deleted. I'll advise him to check for email with pop3 and delete everything in this mailbox regularly...
