Oh... sorry. He said

S> whitelisting: (from man Mail::SpamAssassin::Conf)

and I read that "does not take notice of"
as "ignores", or "doesn't take into account whether it is
whitelisted or not".

Thats correct. So in other words a message is autolearnt as ham or spam or not autolearnt based on the score of the message *without* the whitelisting. This means that whitelisting email does not automatically result in it being learnt as ham whether it is ham or spam or not, as your first message states. That was the incorrect assumption I was attempting to correct.


On the other hand, there is nothing to stop the message being autolearnt if its score before the whitelisting value is added, so for example if a spam would normally score 20 and be autolearnt, and you for some reason whitelisted the spammer, their final score would be -80 and the message would not be tagged as spam, but it WOULD be learnt as spam. (Because it is spam)

Likewise if a message scored -5 before whitelisting and -105 total, then it WOULD be learnt as ham, because its pre-whitelist score was hammy. Make sense ?

And 'man Mail::SpamAssassin::Conf' (version 2.55) says nothing
at all about Bayes.

Oh, sounds like you don't have SpamAssassin installed correctly, because the man page is *FULL* of information about Bayes in 2.55.


There was a "bug" in older versions where I think the man pages were installed to a *different* path than older verisons of SpamAssassin, so if you started with 2.4x and then updated later to 2.5x (I think that was it) then your man command could be looking at the old version.

Have a search in the various man paths on your system and see if you can find old versions of the man pages and delete them...


Your webpage http://www.spamassassin.org/doc/Mail_SpamAssassin_Conf.html
says

It's not "our" web page, both Kai and myself are end users, just like you :)


"Note that certain tests are ignored when determining whether a message
 should be trained upon: - auto-whitelist (AWL) - rules with tflags set
 to 'learn' (the Bayesian rules) - rules with tflags set to 'userconf'
 (user white/black-listing rules, etc)"

This seemed to indicate that only *AUTO*-whitelisting is ignored,
and not explicitely whitelisted addresses with 'whitelist_from'.

Moreover, the entry of whitelist_from states:

"Used to specify addresses which send mail that is often tagged (incorrectly) as spam"

While its documentation doesn't mention Bayes at all, the "(incorrectly)"
seemed to indicate that SA considers mail that passed through because it
is whitelisted is to be considered as ham (and therefore passed to the
Bayesian filter update).

See above, sounds like you're reading the docs for 2.4x


Finally, the mention above of "tflags set to 'userconf' (user
white/black-listing rules, etc)" was read by me as 'white/black-list
rules that appear in the users ~/.spamassassin/user_prefs files
as a rule, or that are otherwise user specific.  Now I understand
the in fact you ar meaning: "USER_IS_IN_WHITELIST/USER_IS_IN_BLACKLIST"
where it *is* clear that 'user' reference the to From: or To: line
rather than a local users (rule).

Thanks for clarifying this.
Hopefully my feedback can help to improve the documentation at this
point though: it is easy to assume that white listed mail is still
classified / auto-learned.  I'd suggest an explicit mention under
'whitelist_from' et al that matched mails will not be auto-learned.

But thats not true though. They *might* be autolearnt, and maybe as ham or spam, depending on what score they would have got without the whitelisting.


I suspect most of your confusion arises from reading outdated documentation pages..

Regards,
Simon
