TMDA Filtering via procmail?
03/11/2003 01:22 AMHas anyone managed to write a procmail recipe that can effectively
identify TMDA auto-replies? You know, the kind that say "To release
your message for delivery, please send an empty message..." Having
never used TMDA, I don't know what's commonly customized and what I
can expect to see there. I note that the header has X-Delivery-Agent:
TMDA/0.62. Perhaps that's sufficient. :0 * ^X-Delivery-Agent: TMDA

around the fact that...

you take the time to learn its quirks. Its new spam-filtering features

04/23/2004 08:25 PMSince I've been using the Powerbook (which I still need to replace
with a newer one now that the "speed bump" is official), I've
drastically changed my e-mail habits (personal mail, not work mail).
In doing so, I wonder if I'm unusual in this respect. Previously, I
was using mutt for e-mail on my IBM Thinkpad running Linux. If you've
not tried it, mutt is really the king of all console-based mail
programs. It excels at making it very easy...
Pre-Filtering The Spam
Pre-Filtering The Spam
06/29/2004 03:54 PMMy anti-spam system now uses a variety of server and client side
filters to help keep the damn stuff out of the inbox. Now, some are
suggesting an even earlier level "pre-filter" for spam. HP Labs has
made a fairly simple discovery that even without
various
email authentication systems, it's pretty easy to get a quick
determination as to whether or not an email is spam. The system they
developed looks at whether or not the server sending you the email
normally sends good emails or sends spam. With that one
determination, they can
properly pre-classify emails at a pretty high success
rate. It's not a replacement for a spam filter at all. They know
it's not that good. However, what it can do is do a pre-sort for
prioritization purposes -- so that good emails tend to make it through
the real spam filters faster. In a number of ways, it's pretty sad
that we now need "quality of service" setups for our email.

Spam filtering, the next chapter
Spam filtering, the next chapter
05/24/2004 09:17 AMI've been experiencing good results filtering out spam with a
combination of Popfile (a Bayesian classifier) and the built-in filter
in Eudora 6. I get well over 1,000 spams a day, so I need
accuracy both in identifying spams and avoiding false positives with
legitimate mail.
The biggest problem with my setup is that it all runs on the client
side. Popfile works as a transparent proxy that runs on my
Windows machine. I don't see the spam in my inbox, but I still
have to download it before it can be filtered. As the spam
volumes have increased, that has become an increasingly significant
burden. Every check pulls down scores of messages, most of which
wind up in the trash. I've had several cases where the sheer
numbers crash Eudora. Getting email through my Treo is basically a
waste of time, because it doesn't have the filters. If I'm on
the
road and don't check my mail, there are thousands of messages waiting
for me when I get back.
I finally had time this weekend to set up filtering on the server
side. Werbach.com and my other domains run through a Web hosting
provider, Pair Networks, which offers a version of SpamAssassin.
The tricky part was configuring it to automatically filter or delete
messages, using procmail, rather than just putting something in the
email header for later processing on the client.
I think I have it working now. I'm using SpamAssassin on a
forgiving setting, because the client-side filters are still running
after the mail goes through. If I can just weed out 60% of my
spams before they reach my machine, life would be much better.
So
far, it looks like I can do significantly better than that.
I'm still tweaking the set-up, so it's possible some legitimate email
will get stuck in the filters. If you write to me and don't get
a
response for a while, please try again.

Collaborative filtering with del.icio.us

There are currently 6550 del.icio.us folk with whom I share common
bookmarks. As nobody will be surprised to see, my link affinity with
that population displays the now-familiar long tail:
There's a recommendation engine lurking in there somewhere, and I've
decided to try to flush it out. The prototype is a two-stroke engine.
First, it captures the set of del.icio.us users on the steep part of
the curve -- the ones with whom I have the most link affinity. Then it
reads all their RSS feeds, coalesces the links, and applies another
filter to select just the links above a threshold of commonality.

ISP Hesitate Over Spam Filtering
06/03/2004 02:24 AMAs the spam battle wages on, most of the focus is on end-users and law
enforcement. Not too many people seem to focus on the role of ISPs,
who
sometimes do take a more proactive role in stopping spam.
The problem, though, is that when the ISP filters spam, they often
run into issues with false positives. If the filters are too loose
(to avoid false positives) then too much spam gets through, and users
are upset. If the filters are too tight, important messages go
missing, and users are upset. Many ISPs are realizing, at the very
least, they need to let the end-user have access to the spam folder,
so they can occasionally sort through it for false positives - but
very few users ever bother to look through it. Some ISPs don't offer
any kind of filtering at all, claiming that they don't see how to make
money off of it - which seems especially short-sighted. If they can
offer sufficient spam filtering, they're much more likely to keep
customers than if they simply let everything through when customers
are looking to their providers to provide protection from the
onslaught of spam. No matter what, it's becoming clear that the spam
fight needs to be approached from various angles, and many customers
are likely to bail out on ISPs that don't at least offer a spam
filtering option.
