I'm inclined to agree.

We use Popefile and Spamhalter in tandem to protect our users from spam, but a few still get through, naturally I suppose as false positives are not things we are prepared to accept.   Occasionally this happens despite a very obvious spam word such as Viagra being on the subject line.   Is there a way to boost some words in the database for either or both filter such that emails containing them would always be spam?

 I have just re activated content control as a way to achieve this for a few specific words I've been asked to handle and maybe this is the way to do this so my query is more out of curiosity really.

With POPFileD and POPFile this is pretty easy, simply create a magnet for the word Viagra in the subject line and send it to the spam category.

Thanks Thomas,

I had not thought of that, although I'm generally a little reluctant to magnet everything as it gets a little hard to manage after a while.   I have been using magnets mainly to whitelist things.  However I could certainly do this for the limited set of words we wanted to block.

 We are currently not delivering email if BOTH spamhalter and Popfile detect them as spam but leaving it up to users to decide what to do with spam detected by only one of the filters.   This works quite well for us as users, generally, already have a filter set up to file spam detected by either filter.

I take it there is no similar magnet feature for Spamhalter?

Correct.  It's the primary reason I'm using POPFileD over Spamhalter.  I do get some very spammy mail from good senders.  ;-)

The whitelist feature of Spamhalter takes care of spammy mail from known senders although of course you do have to keep adding new entries to the list.   You can edit the whitelist for Spamhalter  in notepad once it gets too log for the supplied edit window which has no scroll bar (cntrl end works ok in the supplied window).  

 We use [spam] as our tag for Popfile and [[Spam]] as our tag for Spamhalter, that way its easy to for example detect which mail is spam according to both filters.   I find Spamhalter is better at spam with images etc than Popfile.   But as I said to ALWAYS detect a mail with the name of the male member in its title as spam I have gone back to using content control too.   We use the same whitelist file in Content control as we do it Spamhalter.
 

The whitelist is too limited.  It only works with the senders email address where the magnets of POPFile allow you to create magnets based on the To:, Cc:, From: and Subject: fields.  There are a lot of times where I want to key on something in the subject field, especially when working with spammy Google and Yahoo groups.
