You can use F=1 mailer flag to make sendmail *strip* (remove) null bytes from *headers* before relaying message to cyrus imap. I think that rejecting messages with null bytes (in smtp session) would require using milter. If you use MIMEDefang (perl based/GPL) milter for spam and/or virus protection then it should be relatively easy task.
