I think the easiest way for any MTA to verify the existence of Cyrus 
mailboxes via LMTP is for the MTA to issue the VRFY command to lmtpd. 
This currently isn't implemented in lmtpd, but it would take me about 5 
minutes to do so.  The special "map" protocols that Sendmail and Postfix 
use are nice, but they are overkill for verifying Cyrus mailboxes.
