I'm a bit disappointed that the spam problem is fixed, as I was using it as an
opportunity to try and get bogofilter, which I use with Kmail to filter out
the mailing list spam.

The suggestion I got from the bogofilter mailing list is to set up an
ignorelist.db, in the same directory as the wordlist.db, and the FAQ on the
site gives instructions how to do this as below.

<FAQ>
Can I tell bogofilter to ignore certain tokens?

Through the use of an ignore list, bogofilter will ignore the listed tokens
when scoring the message.

Example:

wordlist I,ignore,~/ignorelist.db,7
wordlist R,system,/var/spool/bogofilter/wordlist.db,8


Because ignorelist.db has a lower index (7), than wordlist.db (8), bogofilter
will stop looking when finds a token in ignorelist.db.

Note: Technically, bogofilter gives a score of ROBX to the tokens and expects
the min_dev parameter to drop them from the scoring.

< This is where I'm confused>

There are two main methods for building/maintaining an ignore list.

First, a text file can be created and maintained using any text editor.
Bogoutil can convert the text file to database format, e.g. "bogoutil -l
ignorelist.db < ignorelist.txt".

Alternatively, echo ... | bogoutil ... can be used to add a single token, for
example "ignore.me", as in:

echo ignore.me | bogoutil -l ~/ignorelist.db
<end of FAQ>

Is anybody on the list using an ignorelist.db with bogofilter, and if so, how
have they set it up?

As far as I understand, and because for example the Debian list is usually
free of spam messages, bogofilter has them marked as ham. The suggestion from
the bogofilter list was to populate the ignorelist.db with headers from
genuine non-spam posts from the Debian list, and in that way, when
downloading email, bogofilter would ignore the genuine messages from the
list, and headers that are spammy on messages from the Debian list would be
processed by bogofilter, and hopefully be classified as spam, and end up in
the wastebin, rather than my Debian-user mailbox.

What I'm unsure about is how to get genuine headers from the Debian mailing
list posts into the ignorelist.db, which is why I asked if anyone is doing
this earlier on in this very long diatribe.

This is all a bit academic at the moment, as the spam flood has stopped on the
list. That is unless someone can direct me to a mailing list that I can
temporarily subscribe to, that is known for allowing spam. If so I can at
least see if bogofilters ignorelist.db is working.

Apart from filtering out mailing list spam bogofilter is working just fine,
and I only get the odd spam, or ham in the unsure mailbox. The rest of the
spam goes straight to the wastebin.

Any help appreciated from those that are using bogofilter, and dealing with
mailing list spam.

Nigel.

Give your address to one of those "refer 10 friends and get a free xbox"
sites. I gave them a disposable email address *once* and that address has
eaten over 13,000 messages since 2005-09-28. (For those of you who are not
math geeks, that's ~16 messages per day.) A different disposable address
given to a similar site has eaten over 3,200 messages since the same date,
which is ~4 per day.

Or make a post to one of the *.test Usenet groups. That will get you
all the spam you can handle within a few days.

If you can't help with the problem I have, why reply with some sort of pisch
take.

I am genuinly trying to resolve the problem of filtering out spam, that
occasionally turns up on mailing lists. As I've said bogofilter works fine
with non mailing list spam, but something extra is needed to deal with
mailing list spam.

I do not think that spam is funny, and something to laugh at. I check my
wastebin each day after downloading the mail, just to see that no ham has
been put there by bogofilter. Most of it has do with getting a bigger male
member, expressed in a variety of ways, some of which are extremely crude,
and quite obscene. Often I just empty the trash without checking it, as the
spam that's there is to say the least "sick".

Perhaps I should just keep this problem on the bogofilter list if the best
that can come from the Debian list is what you have posted.

I use Sarge, Etch, and Lenny, along with Fedora installs, and other distro's.
Apart from FC2 that I'm emailing from I find the Debian ones, and Archlinux
the most stable. I'm upgrading Sarge at the moment, and am surprised that I'm
not only getting security updates, but also updated packages, so that's a
darned site better than Fedora are doing.

Rant over.

Nigel.

I didn't know that's what you were looking for; now I do. You rushed to the
assumption that I was trying to be obnoxious, or at least that's how your
reply came across, while my message was intended to be nothing of the sort.

I don't believe I am wound up. Some time back we had an influx of spam on

I understand this, but your reaction was akin to a slap in the face after I
simply tried to be somewhat humorous while providing what I thought was a
helpful suggestion. I ask you to reread my post in this light.

Noted. (I usually do this, though I am admittedly a bit lazy today.)
