RE: enable spamassassin? - Cube - 02-22-2009 07:07 AM
Rbtux is right. I also don't like Maia. And the actual amavis version is able to do some other useful things like DKIM verification and signing. But I don't reject spam, I tag it and move it to a special IMAP directory afterwards. You know this procedure perhaps from some freemailers like GMX. Additionally there is a special spam e-mail-address, where my costumers can send their not recognised spam to, so it gets learned by the Bayes filter.

Yes, your full right!
I will test your Version, too.
But first i want to try dspam on a FreeBSD host

In my experience this spam folders are not the best solution either. A lot of mails lay in there for a week or two because the customer forgot to look ;-)
With autolearning I would be very very very very careful. We did this once with a spam folder where users could move mails to be learned as spam to. Problem is the user also thinks the newsletter he subscribed to and he doesnot remember is spam...
This will messup your bayes filter....
bayes are self-trained and that leads to much more accurate results in my experience. But this of course depends on the customers and the type of spam you have to deal with in general...
about the tagging thing:
as you may have seen:
$sa_tag2_level_deflt = 5.8;
$sa_kill_level_deflt = 6.41;
with tag2_level you define the score needed to be tagged as spam, kill_level defines the score when mails are rejected. In our company we use 6.0 und 6.9. 6.9 is very conservative and I don't think we actually have false-positives with this settings... 90% of mails are rejected before they reach spamassassin anyway...

They can not forget because they get a daily report about the filtered spam.

You're right. I know that I can make this with my customers, but I wouldn't do this if I would offer hosting for everybody.

This self-training is actually called autolearning.
The important thing is that there is only one Bayes database and not a seperate one for each user - like it is done in Maia AFAIK.
Quote:$sa_tag2_level_deflt = 5.8;
I tag already at 4.0. False positives can happen, but are very, very rare.

So in this setup, are you not running spamd? I don't see where spamassassin is tied into the setup...
RE: enable spamassassin? - Cube - 02-23-2009 05:01 AM
Spamassassin is called by amavis.
RE: enable spamassassin? - rbtux - 02-23-2009 05:39 AM
spamassassin is called as module within amavis...
you configure it in amavis conf files with the vars that begin with $sa...

But the normal spamassassin config files are also relevant.

Ah ok. Thanks. I'll play around with this and see what i can get running.

Hi - is there any way to test if this is working? I have checked my mail headers on a received mail and dont see any spam headers, I though spamassassin always added them. if not, is there a way to check spamassassin is working?
thanks for the helpful setup
