Hi there. I'm trying to enable recipient verification at the MTA (Sendmail 8.12.11) level so I can reject mail (mostly viruses) addressed to nonexistent recipients. I'm using Cyrus IMAP v2.0.17 on my primary mail store, which is on the same box as the MTA.
Currently, sendmail accepts the message even if there is no cyrus mailbox defined for the recipient, and then attempts delivery via LMTP. Since the recipient doesn't exist, the delivery fails and Sendmail generates a bounce message which is queued and a copy generated for the postmaster. Is there some way to configure the MTA/LMTP interaction to check for local recipients during the SMTP conversation instead? My Google searching produced the possibility of adding 'w' to CYRUSV2_MAILER_FLAGS before building sendmail.cf, and when I tried it on my test installation (Cyrus IMAPD v2.1.16) it seemed to work just fine. However, when I enabled this flag for v2.0.17, *all* local mail was rejected whether the cyrus account existed or not. Am I on the right track? Can I even do what I want to do with v2.0.17, or is it necessary to upgrade to v2.1 or even 2.2 for smmapd support?
