G'Day

I've probably missed something obvious and simple, but I'm starting to chase my tail in searching for the answer so I've decided to ask the list...

I'm using the full courier system on a test server running RedHat 6.2 (Looking to deploy if it holds up.) I compiled it into a an RPM (Just using rpm -ta) on another almost identical machine (The only real difference is the video card.) and used the stock standard installs.

The problem is delivery to local users, the SMTP does not seem to recognise the local users exist. When EXPN and VRFY are enabled addresses for user@local.domain show Not Found. All aliases of the local domain appear to resolve fine, as do aliases for virtual domains[1], however when final delivery is attempted it bounces the E-Mail. All other modules (imap, pop, webmail) can see the local users, access the Maildirs and as far as I can tell operate fine.

I have tried no filtering, and the default maidrop filters on both esmtp and local (In /etc/enablefilters) I have also tried setting the DEFAULT delivery to maildrop and ./Maildir without any luck.

Can someone please tell me what I missed, or any standard silly mistakes that could cause this as I'm starting to tear my hair out.

TIA

Regards

Glenn.

[1] an entry in the aliaes file that points @virtual.domain at user, then when it recives an address of user@virtual.domain it tries to deliver to user-user@local.domain but then fails to look up the .courier files...
