Auto-Learing is turned on by default. This is done in
/etc/mail/spamassassin/local.cf or where Your site config usually
resides. It could be overwritten by the file
~root/.spamassassin/user_prefs, if spamd runs as root.
I assume that suid arguments are not used in Your configuration.

Tell these people that establishing spamfilter takes a lot of time and
will never be 100% reliable. Never. Either they have to expect some
spam, or they have to expect mails incorrectly declared as spam and.
Auto-learing of spamassassin (and others) takes really time.
I set up an email account "spammaster", where people report spam
manually to by just forwarding spam.
I also set up a filter that attaches spam into a new mail and forwards
it to spammaster. That filter is also able to do pattern matching
with perl regular expressions in mail headers and bodies. If matches
are found, mail gets attached to a new one and sent to spammaster.
Users will never see mails found to be spam by spamassassin or by my
filter.
This is a very strict solution, normal mails might never reach users.
However, Users reporting spams to the spammaster account could help
You to set up more rules for spamassassin. E.g. blacklists or filters
with scores.
But someone has to review spammaster account...
....so I also started another filter that will act as a
blacklist/whitelist operator for users. They can send eg.
ADD BLACKLIST [EMAIL PROTECTED]
to that filter and the address gets blacklisted. Same for
whitelisting. Furthermore, target mailaddresses could be automatically
whitelistet by that filter, if the sender comes from Your domain(s).
These things are not difficult to implement, but it can be dangerous
using them.
Let me know if there is an interest here.
> E.g. how do I know that mail gets filtered now ?
Did You run XMail as follows from command line:
--- cut --- one line:
XMail -Pl -Sl -Ql -Yl -Fl -Cl -Ll -Md 2>&1 | tee /tmp/xmaildebug
--- cut ---
This logs nearly everything to XMail log files. The daemon itself will
stay in the foreground and write a lot of debug messages. They can be
seen in Your terminal and they will go to /tmp/xmaildebug for futher
work.
Stop xmail with CTRL-C after a whhile and put it back to normal mode.
Review /tmp/xmaildebug, look for sa_filter.pl.
Bye,
Hagen
