Qmail problem, clients can only check/send mail

clients can only send messages, the messages don't get delivered to the address, but they can check their email. I've installed vpopmail with mysql support and everything as far as adding users and the clients checking their account works perfectly. Except of course they cant receive messages.

here is the output of the log from /var/log/qmail/qmail-send/current,

Thanks in advance.

What you talkin' 'bout Willis? ... They either get mail or they don't... Do they sit in the queue?

THAT IS A PROBLEM...

Can your peeps send emails to each other? that would indicate that email server is working on your Intranet, just not in the wild. That would indicate a DNS issue.

let us know...

thanks for the reply, sorry for not being clear about things. But the good news is i figured it out, the domains in vpopmail were corrupt. Cause i deleted the domains, re-added them and now everything is running perfectly. Thanks to the guys in #qmr on debian.org
