Hi

Is there a way to define in the keyword list that it should only match the word if it stands alone?

Example:

I have "sex" in my keyword list. But if somebody writes msexhange in the e-mail, the mail will be qurantined with a hit on sex ???

I believe if you want to encapsulate spaces or other non standard characters in the string you can list the keyword entry like this:

( cialis )

Then the match must include the spaces.  This would resolve your issue.

Maybe Robert can confirm or deny on this.

Im sure that's a part of the soloution.

There's a litte problem with the

( keyword )

ex:

If keyword is the only word on a line, with no spaces before or after the keyword, it will be let through.

We could then of course make 3 entries:

(keyword ) -no space before

( keyword) -no space after

( keyword ) - space before and after

So that if keyword is on start on line or end of line, or in the middle of a line (with space before or after) it would be caught. But that still doesen't solve when keyword is the only word on a line without spaces before or after.

I used to run a Norton spamfilter, with that we should have the keyword in "" ex:

"keyword" which told the spamfilter to catch keyword in all 4 cases. Without taking it when it was in another word ex

"sex"

Then msexchange would not be caught.

To summarize.

Originally I got a lot of false positives when having the word sex in my keyword files.

Words like msexchange would hit on that word.

The another user said to use ( sex ) instead, and I have put a bit of work into that.

Found out to make 3 entries for that (actually 6, also have them with Subject: in front):

( sex ) - take out sex if there is an space before and after (hit on: do you like sex my frind)

(sex ) - take out sex if there is an space after (hit on: sex is a bad thing)

( sex) - take out sex if there is an space before (hit on: du you like sex)

Then I don't get any false positives anymore. But now I have opened up to get potential spam again. Because now when the word sex stands for it self on a line in either subject or body the message gets trough my spamfilter.

Is there a way to get this fixed?

Maybe Logsat would make a change in the spamfilter, so there's a way to define in the keyword list that it's when the keyword stands for itself and not as a part of a word.

Hope You get my point, or please feel free to ask!

I understand your dilemma and can see the need. The problem is that if all you have to work with is "sex" on it's own line and no other offending words, you really should not be expecting to use keyword filters to block.  Keyword filters are likely the most processer intensive blocking method used in SpamFilter. If you can't use keyword combinations ie (sex, hardcore) without the parens, you should stick to words that are not really words or that can easily identify spam.  Then focus on other blocking mechanisms in SpamFilter that are less processor intensive.

I do not advocate the continual addition of features and programming because of the additional processing time it already takes to process emails.  SpamFilter is very fast, depending on how you setup, but to keep adding more processing logic naturally is going to force us all to keep upgrading our hardware, etc.

Try

(^sex$)

Thankyou very much.

That single entry in my keyword list solves my problem.

Instead of 3 entrys with a opening for a single word on one line. The entry (\bsex\b) takes out everything and not when inside other words ex: msexchange.

Again Thankyou!!!

A happy christmas and new year to you all (without spam<:-) )
