In particular, is there any clean method for an MTA like exim to determine whether a given local part is deliverable via the Cyrus lmtpd? (Or, more accurately, would it be deliverable if sieve were turned off and there are no problems with quotas, etc.) I am particularly interested in being able to do so with local parts which contain detail notation for submailboxes. (E.g., 'patl+cyrus.users')
Er... Whats wrong with just attempting delviery of the message?
Because if it can't deliver to a Cyrus mailbox, then I want it to go ahead and try something else. But by that point it is too late; the cyrus router has already accepted it.
Or do you want your MTA to reject the message during the SMTP session and not bounce it later?
If you want the later situation, you might be stuck.
Yes, I also want to check for a valid address during the verification pass; which may happen during ACL checking while the SMTP session is still open.
