Debian incoming mail disappearing
 

I am running debian sarge, with exim 4.

All incoming emails disappear, with no errors in any logs that I can find. Even if I log into mutt and send an email to myself it does not arrive. the same happens with squirrelmail.

All emails are sent ok and arrive as sent from the correct address, I can telnet into the mail server, but no messages are there.

Appreciate any help, I have a feeling that the problem happened after the domain name was changed on the deb box. All refrences I can find relating to the domainname have been changes.
