Description Boris de Laage 2005-07-23 12:12:31 UTC
Please describe the problem:
Spam filter doesn't work well. The *same* mail marked as junk more than 30 times
(I receive this one every day) is still left in the Inbox.
Even after 6 month learning, Evo filters only 1/5 of the spams. TBird is *much*
better in that job.

Steps to reproduce:



Actual results:


Expected results:


Does this happen every time?

blame SpamAssassin, we just use that program to filter spam.

btw, you need to train both HAM *and* SPAM, not just spam.
Comment 2 Boris de Laage 2005-07-24 13:38:04 UTC
I think you missed the point.

Evo may delegate this task to spamassassin or anything, I don't care. The fact
is you advertise a feature (
http://www.gnome.org/projects/evolution/features.shtml )  which doesn't work
properly. You implement it the way you want, I just give you a "user feedback"
on this feature. But if you don't give a s*, well..

"Baysean-based junk filtering withoptional remote rules get rid of all of the
emails which bug you most." Missed. Enlarge your penis & friends are still there
every morning.
Comment 3 Jeffrey Stedfast 2005-07-25 13:17:24 UTC
did you train both ham and spam?

do you have spamassassin installed?

I bet anything the answer is no to at least one of the above questions if you
are having that problem.
Comment 4 Luis Villa 2005-07-25 13:24:14 UTC
You can train ham in evo? How? (And why, given that I don't have to do that in
gmail or mail.app?) Sounds like, worst case scenario, you guys have a serious
usability problem if *I* didn't know you were supposed to train ham, or how.
Comment 5 Jeffrey Stedfast 2005-07-25 13:29:22 UTC
uhhhh... that's how bayesian filters work.
Comment 6 Luis Villa 2005-07-25 13:31:17 UTC
See also bug 309181- this isn't the first bug filed about this, and certainly
fit with my impressions when I could still use evo. (*mumble*crappy mail
provider now*mumble*)
Comment 7 Luis Villa 2005-07-25 13:32:20 UTC
yes, I know that, Jeff. I'm not a complete idiot. But some people (apple,
google, etc.) train their bayesian filters for ham automatically. So surely you
guys can think of somehow to do that as well :)
Comment 8 Boris de Laage 2005-07-25 13:57:16 UTC
Jeffrey, to answer your questions : yes. SpamAssassin is here, and I've been
marking spams for a *very long* time. I also run "sa-learn --ham
.evolution/mail/local/Inbox" when everything is clean (and when I don't forget to).

There is an issue when you push this feature on top and it's actually barely
usable. I shouldn't have to run "sa-learn" by hand. And "switch to TBird then"
is *not* the solution.

Ok, I've been a bit grumpy. Maybe because I've lost 695Kg, but at least now I've
got 579845 green cards.
Comment 9 Not Zed 2005-08-02 05:49:43 UTC
note: we developers didn't push this feature to the top.

i never thought it would work in the first place, and don't imagine how it could
be fixed.
