Add two new accounts/groups for sendmail:

Browse Source 
smmsp - sendmail 8.12 operates as a set-group-ID binary (instead of
set-user-ID).  This new user/group will be used for command line
submissions.  UID/GID 25 is suggested in the sendmail documentation and has
been adopted by other operating systems such as OpenBSD and Solaris 9.

mailnull - The default value for DefaultUser is now set to the uid and gid
of the first existing user mailnull, sendmail, or daemon that has a
non-zero uid.  If none of these exist, sendmail reverts back to the old
behavior of using uid 1 and gid 1.  Currently FreeBSD uses daemon for
DefaultUser but I would prefer not to use an account used by other
programs, hence the addition of mailnull.  UID/GID 26 has been chosen for
this user.

This was discussed on -arch on October 18-19, 2001.
