[Dovecot] Missing deliver

I've installed Red Hat Enterprise Linux 5 on a new server. I'm configuring sendmail and dovecot; however, /usr/local/libexec/dovecot was not created when I installed the dovecot rpm (rpm -Uvh dovecot-1.0-1.2.rc15.el5.x86_64.rpm). The problem is I can't find the deliver executable which is supposed to be in this directory. Any help would be appreciated.
