Is there a way to forward and keep mail?

[Matt Bonner]

Okay, that subject isn't very well worded.  What I want to do
is have incoming mail go to two places.  For example, someone
mails me at this address (mbonner at oscar.hns.hac.com), and one
copy of the message will stay here, and one copy will go to
another account.  If you think most people don't care, email
me and i will post a summary.

Thanks (i hope) in advance,
matt
