sa learn with hundred of users on a gateway box

[Chris Campbell]

I was wondering if anyone has a similar situation....
I have 4 mailscanner boxes that are in the DMZ ... merely scan for virii
and spam, then forward on ...

I need to setup some sort of spam email account so that users can forward
and sa-learn can do its magic.
I currently have a spam acocunt setup, that has over 2000 spam messages
from various users....but the
question is:

Since these emails are already forwarded from an internal user...won't this
mess up sa-learn?  The FROM will always
be from user at ourdomain.com .....

Is anyone else in a similar situation..and does anyone have any opinions?

Thanks.
