I'd like sendmail to check presence of the cyrus mailbox during establishing SMTP connection. If the cyrus mailbox doesn't present sendmail drops SMTP connection (doesn't recieve email). What have i to write in sendmail.mc file?
There's a page about it here:-

It is nice to see that somebody knows about my rtcyrus existence ;)
RTCyrus requires sendmail patch (new custom "file" map) but sendmail.org was "reluctant" to accept it.
Unfortunately, this relies on giving sendmail knowledge of the internal arrangement of Cyrus mailboxes, to check for the existence of the user. I've avoided implementing it, as I feel it goes counter to the idea of Cyrus as a "black box", accessible via IMAP/LMTP/POP only. As such it'll only work where sendmail and Cyrus are on the same machine.
If there are any better ways to achieve the same end, I'd also be interested.
There are two alternative approaches I can think of right now: 1) custom milter [servicing only "RCPT TO:"] 2) socket map [ available in 8.13 preview http://www.sendmail.org/8.13.0.PreAlpha4.html ]
Both will make sendmail ask separate process (which may be located on another server) if the given envelope recipient address should be accepted.
IMHO socket map will be a better solution of the problem: Are you interested in testing simple perl based "socket map" server for cyrus? [ and testing sendmail 8.12 of course ]
