Hi,
I had nothing much to say or ask when I started writing this email but now
that I've thought about it ... do any of you have any experience with
commercial anti-spam solutions?
Of particular interest to me are Roaring Penguin's CanIt and
Sophos/ActiveState's PureMessage? To a lesser extent I am interested in
commercial RBLs such as MAPS and their effectiveness versus the free RBLs (I
use sbl.spamhaus.org, bl.spamcop.net and relays.ordb.org).
*Any* other commercial or non-commercial solutions that you find effective I'd
like to hear about.
I ask about commercial solutions because they usually come with management
interfaces that I do not have the time to write currently. AFAIK, pure open
source tools like spamassassin do not have anything other than text config
files and command line invocations. Clients mostly seem to prefer GUIs. I
would love to hear about mangement interfaces for the open source tools that
I might have missed.

When this beloved virus first came out I had the pleasure of being one of the
early recipients, to the tune of 200 copies per day.
I took Henry Spencer's suggestion of blocking all email greater than 140000
bytes and that was 100% effective, today my mother was trying to email me a
few pictures and it was over that size, off came the block, back came the
viruses.
I use bogofilter to filter out my spam and it is happily detecting these
viruses and putting them in my spam folder, along with the hundreds of
idiotic messages stating that I have sent a virus and regular spam. However
at an average of 145K each that about 900MB of this virus per month that I
will be receiving, I don't believe that I should be the one paying for that
bandwidth.
I know that I can solve this problem by putting the size limitation back into
postfix but there is legitimate email that approaches that size without
having large executable attachments (check our the barfs on a freeswan list).
Do we just have to get used to the idea of trashing 10 emails for every
legitimate one (as is often the case with snail mail)? What will happen as
more computer illiterates come online with their incompetent operating
systems? Perhaps the solution is to make everyone go back to communicating
at 9,600bps?
