Using cyrus as local mailer makes sendmail accept messages to non existing 
cyrus mailboxes (accept now, send bounce later) UNLESS you use RTCyrus2.

I personnaly suggest keeping mailbox data in one place (LDAP). It allows to 
avoid "lost data synchronization" problem. "Inbox autocreate" patch simplifies 
further the administration.

P.S. Some spammers send "dictionary recipient" spam so "accept now, send 
bounce later" may consume a lot of your server resources and keep a lot of 
bounce messages in your server queue.
