I've got a machine with three or four jails on it. I'd like to run
sendmail in all of them. One jail will do Mailman, another will do
email forwarding for clients, another will have an imap server in it,
etc.

On the host itself, I have in rc.conf: sendmail_enable="NO", instead
of "NONE", to allow cron stuff to get mail out.

I'd like to have sendmail_enable="YES" in each of my jails. Right
now, sendmail doesn't seem to want to start in my jails with ="YES".

Is it necessary to tell sendmail inside a jail to listen only on that
jail's IP? If so, how is this done? I'm hoping a line or two in the
.mc file will do it, but I'm new to editing these files.

Is there a problem with the localhost sendmail config being shared
around the jails, since localhost really belongs to the host itself
(if I understand localhost correctly)?
