Great question! I know there has been some discussion to be able to
choose your base MTA upon install but I don't know how far this has
I don't use that option but rather install it as a regular port,
register it in mailer.conf when it asks you to and then do this in
your rc.conf


I haven't used the INST_BASE option out of fear that it might give me
trouble on building world and upgrading. Also a new approach I'm
taking is using EzJail for "service jails" so use a pure MTA jail and
use the base sendmail as a relay to that. For the time being I'm using
posfix on the base system to relay  but in the future I plan to do it
with the native sendmail and only use postfix on the MTA service jail.
