Using Cyrus 2.1.12 and sendmail 8.12.6, I would like mail for all unknown users to be delivered to a specific mailbox. I've tried setting LUSER_RELAY, but since sendmail hands off all local mail to Cyrus, the LUSER_RELAY is ignored. I do have confLOCAL_MAILER defined as cyrusv2.
I found a very old message here suggesting a trick with rulesets and a text file containing a list of all IMAP users. I also found a patch from Carsten Hoeger this past August (which was never incorporated into the main sources) that adds an lmtp_luser_relay option to imapd.conf. Are these still the only way, or is there a more correct way to do this? If not, any chance that this patch could be incorporated into Cyrus?
