Filter to Delete mail in Sent Folder

[Susan Lewis]

With a pre-configured filter, I bounce much of my mail to a separate
account outside of PMMail 99.  However, it copies the e-mail to my Sent
folder and is clogging up our network drive since it registers 2 copies
for every outgoing e-mail.  Is there a way in PMMail 99 to prevent or
automatically delete (via a separate filter) any piece of e-mail that
shows up in the Sent folder that is addressed to this other e-mail
account?

Anybody out there have any ideas?  I would be forever grateful!
