All by itself? No. I tell it. Any virus matching the regex pattern I
set up in the config file doesn't generate reject notices. It's as
simple as that.
If you really want to dig in to how this software works, I suggest you
do so - it's all free an opensource (GPL'd, I think) - google for
amavisd-new. It's powerful stuff, tied in with SpamAssassin.
Manually sending a mail to warn someone known to you to warn them of
whatever problem is fine, good, commendable and for all good people
expected.
Sending what is effectively (miss-directed do-gooder) spam to unknown
strangers is silly and likely an example of your being duped. It adds to
an exponential growth of the problem symptoms.
Oh, I see. They can tell the difference between email I type and email
my server automatically sends.
Since I (the postmaster) am notified whenever my server is sent a virus,
I can quite easily (and I do) check to see if the virus forges the FROM
and Return-Path headers. If it does, I add it to the blacklist so no
more notifications are sent out. Admittedly, the first one does go
out, but I think it is a small price to pay.
Has anybody figured out yet, for sure, if the Return-Path header is
forged on Swen-generated emails?
