We have implemented qconfirm on a test basis by user as we already have
qmail-scanner,spamassassin and clamav running.I am also eager to rid our
system of double-bounces even though we have not taxed the server from this
standpoint.

Are the un-wanted e-mails to a user base across the board (you stated random
users@domains), or is there a possibility of some pattern ? The latest
spamassassin has included a Bayesian filter, and I will be testing this and
looking to reduce UCE.

Subject: Spam Bounce Control



Greetings,

We have recently seen a very large increase in the volume of
spam originating from Brazil and Asia.  The majority of this
spam is addressed to random users@domains which reside on
our systems.  The purpose is to 'guess' valid email
addresses I'd imagine.  Anyway.  I am seeking multiple
solutions to control the bounce handling.  Since the return
addresses are forged and do not exist, the bounce will
double-bounce and cause additional waste of resources.  We
are running Qmail and tried the tarpitting method to
regulate mass mailings from any single IP address, however,
the most recent volume of spam is from thousands of unique
IPs from different networks apparently working together
(spam bot?).

If anyone else is running qmail and have any spam or bounce
control suggestions- I'm all ears.  I've looked through
qmail.org's page about spam control, and we are currently
implementing most of those solutions already.

Thanks!
