Hi Gabrie,
Check out the HTML code in your spam. The criminal spammers are aware of
Bayesian filtering and they are including text from books, articles etc.
that are not "spamoid" in an attempt to trick the filters. I think the
only way to stop spam, in the end, is a thick rope tied to certain
"Texas" specifications ;-)
If you see a spammer on the street, I trust you'll know what to do with
him. Be sure you get the names and locations of at least five of his
associates before you're done.
HTH,
Tom

Hi
I'm evaluating GFI Mail Essentials right now. The latest version has
Bayesian filtering which is a hughe step forward. At the moment Bayesian
filtering is considerd one of the best methods to filter out spam BUT it
does take some effort. Actually, the more spam you get, the better the
filter gets.
What I have done for my organisation:
- Created a user SPAM . Told GFI to forward all spam to that user.
- Created a folder called HAM and a folder called FALSE SPAM.
I told my users to regularly check the SPAM folder and if they find
e-mails that are not considered spam to them, they could drag it to the
HAM folder. If in their normal mailbox they receive an e-mail which is
spam but not considered spam by the filter, then they should move the
mail from their mailbox to the HAM folder.
Once every few days, I use the Bayesian wizard to update his settings
according to the HAM and FALSE SPAM folders. And I must admit that we
get less false positives every time.
Since 14th oct, we have received only 2 false positives, 6 mails that
were not marked as spam but should have been and over 500 SPAM mails.
In the beginning it was much worse. So a Bayesian filter gets better
every time you teach it.
And now you should just look for software that has a great interface to
your bayesian filter. Ofcourse, other filters are also needed, don't
forget about them.

Anyone have any points they'd care to share as to why they'd choose one
of these products over the other? The need is to have a centralized spam
filter that prevents any and all spam from making it to the users inbox.
Also don't want to have to sit and add entry after entry of items to be
filtered. GFI wins on the pricing being that I only have 25 users.
I really would like to know how most feel on this.
Thanks
