[vchkpw] Re: [vpopmail] handle 'postmaster' as non existing user (reject mails)

You're right but I think RFC822 should be worked over. Problems with UBE and SPAM were 1982 not even theoretically existing. I'd like it better this way: I have several domains with the same MX RR(s). The domain the MX host(s) belong to has a case insensitiv 'postmaster' mailbox. It is filtered for SPAM/Viruses (rejected with a meaningful message) and checked once a day. Most if not all problems the appropriate clause in RFC822 is defined for are technical by nature. For all other concerns this account can help too. regards Lars

Under case 10, it actually does the user check, so just have it test the user for 'postmaster' and return a failed 'user does not exist'. It could be more easy to set the BOUNCE_FLAG on for each postmaster, and message will be rejected. That's it!
