It's unclear what you mean when you say "problems getting sendmail to check
whether a recipient actually exists".  Are you saying

 	1) During SMTP delivery, sendmail complains a user is unknown?

 		RCPT TO:<user at domain>
 		550 5.1.1 <user at domain>... User unknown

 	In this case, it has nothing to do with dovecot.  You'll
 	have to check your sendmail configs on user map lookups.

 	2) The LMTP can't deliver to a user's INBOX?  If this is what
 	you're complaining about, you ought to supply

 		i) log entries demonstrating the problem
 		ii) a hint of your configuration i.e. doveconf -n
