I'd suggest you look at the daemons being started from scripts in
/etc/rc.d and see if they are responsible. In particular, see if
sendmail is set to check its queue at intervals (-q Nm); if the
machine is permanently networked you can set that to some suitably
high value, and if its external connection is intermittent you can
turn it off in rc.d but put something like this

if [ -x /usr/bin/sendmail ]; then
        sendmail -q &
fi

in /etc/ppp/ip-up to flush outgoing mail on connecting.
