I need help with procmail. what I would like to do is forward all

This sounds like begging for trouble. But if you don't mind the risks,
you don't even need Procmail for this. The plain old .forward syntax
of Sendmail has everything you need.
Let's say your local login name is "gblum", and you would like to also
forward to "marc(_at_)example(_dot_)com". Then you'd put in your .forward file
this:
marc(_at_)example(_dot_)com
\gblum
# notice the backslash there! Prevents Sendmail from looping
Mail loops are a more serious problem than you might think. If you
were to set up a similar arrangement at both accounts, the mail loop
you thereby create will mail bomb the weaker server back to the stone
age.
This, of course, is where Procmail comes in handy; it lets you
+selectively+ forward mail.
:0
* ! ^X-Loop: marc\+been-there-done-that(_at_)example\(_dot_)com
| formail -A "X-Loop: marc+been-there-done-that(_at_)example(_dot_)com" \
| $SENDMAIL $SENDMAILFLAGS marc(_at_)example(_dot_)com
This will add the X-Loop header and forward to marc(_at_)example(_dot_)com only
mail which does not already have this X-Loop header. That means the
mail on the two accounts will not be +exactly+ identical, because the
headers will be different (but they will anyway -- your local
Received: lines will be different, too).
Most of this is in the procmailex manual page, by the way.

Please turn off this "feature" in your "mail program". Thanks.
Hope this helps,
