Greenman:
I've checked the information as you suggested. The postmaster account is a username: admin without a domainname.co.uk The local domains are included in the list: apsarchaeology; apsarchaeology.co.uk; lincsheritage; lincsheriatge.org and there are no filters setup which forward mail from the admin (Postmaster) account.
If you're not on Netware, there are the file-based forwarding lines which could deliver mail intended for postmaster. Check in the c:\mercury\mail\admin directory for a file called forward. If that exists, autoforwarding is on. Read it to see where it's going. You'd've created that file yourself, though, so you'd probably already know. But at least make sure that the c:\mercury\mail\admin (or wherever it would be) directory exists and that, in your pmail.usr file in the c:\mercury\mail directory, there is a line for "admin". Maybe when you set up Mercury you set the postmaster keyword but didn't create the mailbox somehow. (If you have a local account yourself, might as well just make postmaster that local user and handle mail directly rather than retrieving it from a separate mailbox called admin; in that case, delete the admin mailbox and user using the user management dialog.)
Otherwise, I fancy I've run out of ideas and you've definitely found some sort of weird bug. You'd want this working, though, so that you can get status messages both from outside and inside the mail system itself.
Cheers,
Sabahattin
