In this case you could modify the smtplib.pm, or you could do it as I
described earlier but
instead of calling sendmail you would call the functions from the smtplib.pm

I don't know if you use Windows as a server, but when not it would be
simple (on todays
Linux distributions) to install sendmail to handle the outgoing mail and
contact another server
using SMTP to actually deliver it.  Usually you only need to tell the
system that it is a leaf node
that sends all mail to a "smart host".
I use SuSE Linux, and there you need to fill in one or two screens and
it all works out of the
box.
