Try fetchmail. it's perfect for this.

1. In /var/qmail/control/smtproutes, add :your.isp.mailserver.com
(flavor the path, to taste.)
2. Add a script called /etc/ppp/ppp-linkup (IIRC this is the script fbsd
executes upon creating a ppp connection) simply have it send qmail-send
an -ALRM signal (killall -ALRM qmail-send will work nicely on fbsd)

Qmail will do this by default. if it can deliver locally, it will
regardless of the dial-up connection.
