To use dovecot's deliver as sendmail's local mailer you need the following
lines in your sendmail.mc:

FEATURE(`local_procmail', `/local/dovecot/libexec/dovecot/deliver',`deliver -d $u')
MODIFY_MAILER_FLAGS(`LOCAL', `-f')

1) Change path to dovecot's deliver to fit your installation.

2) The second line is needed only if your deliver does not support 
"-f envelope_sender" command line argument or if dovecot and sendmail do
not "play well together" with "empty" (<>) envelope sender.
I do not think it is required but http://wiki.dovecot.org/LDA/Sendmail
mentions it for some (unexplained) reasons.

3) the above changes should not affect deliveries to virtual users
   [ unless you use *VERY* unusual sendmail configuration ]

P.S.
Do you reject messages to non existing virtual users in reply to "RCPT TO:"?

Gauls! We have nothing to fear; except perhaps that the sky may fall on
our heads tomorrow.  But as we all know, tomorrow never comes!!
