Greetings to all.

I have (what is to me) a very unusual problem.

I've had exim up and running for 2 years now without a hitch. I have
virtual users, virtual_forward files and spam assassin working just
fine. However, now I have a client who wants a forward file AND
spamassassin.

It works like this:

me@??? <---alias pointing to:

me@??? <---main email address. This has a forward file that reads:

me, my@???

me@??? is also set to scan for spam. (Not all accounts use
spamassassin so I keep a file of accounts to scan for each domain)

So virtual_forward of me@??? sends to me@??? and my@???
It also fires the spamcheck_director for me@???.
The forward generated by the forward file comes through as me@??? and
fires spamcheck_director again.

The end result is for any message going to me@???:
me@??? gets 2 copies
my@??? gets 1 copy.

How can I set it up so that me@??? does not get 2 copies?

Any help would be greatly appreciated.

TIA,
=C=
