run "nslookup -querytype=MX yourdomain.com".
do you have the MX configured correctly ?
compare it to "nslookup -querytype=MX google.com"
Cheers, Tom.

Question

looks to me like all the mails that cannot be delivered to do not have MXes configured:

Quote:
Non-authoritative answer:
telekbird.com mail exchanger = 0 .
so it's no problem with your server, but the email addresses are invalid...?

Cheers, Tom.
