Subject:   confusing sendmail_*enable settings in /etc/defaults/rc.conf

 After installing a 4.4-RELEASE machine I was surprised to notice sendmail
was accepting connections. Apparently, if you choose the "medium" security
profile and then edit rc.conf to enable the sendmail_outbound* variables,
you're not running in outbound-only mode.

A quick look in /etc/rc reveals that sendmail_enable takes precedence over
sendmail_outbound_enable. Since sendmail_enable is YES in
/etc/defaults/rc.conf, you have to first set it to NO if you want to use
sendmail_outbound.

 That seems confusing. Doesn't it make more sense to either unify the flags
and kill sendmail_outbound (so there'll be a commented line in
/etc/defaults/rc.conf along the lines of:
# sendmail_flags="-q30m"   # use this for outbound sendmail 
?

 Alternatively, we can make /etc/rc consider both sendmail_enable and
sendmail_outbound_enable and warn if there's a conflict. Or even allow
sendmail_enable to take on a new value, say "OUTBOUND".
