[Dovecot] triggering multiple actions on pop-3 request

Yet another model, if you don't need the first LIST to block, would be
to write a simple script to "tail -f" the dovecot log file, watch for
successful auths, and then launch fetchmail for that user.  Could be
done in Perl in about 20 lines :)
