I know it's not exactly the solution to your problem, when you don't
want the mail, but I find that using the mail/ssmtp port for local
mail in jails is pretty nice.  There is no deamon running and I can
have one config file in all the jails which says that ssmtp should
relay the mails to a real mailserver.

(Might be useful for other people building jails.)
