Temat: [exim] Black Copy filtering problem
Hi there,

Our SpamA version is: 3.0.3 Running on Perl : 5.8.4.
Our serveurs only run Debian, stable, and are up to date.
We have got exim4, clamscan, and SpamA. But we do not use any Procmail.


Since our mail server (www.mezimail.com) is supposed to be opened (free
service to promote OpenSource solutions), some spammers tried to create
accounts and sent spam from there.

So I searched (a lot) for solutions. I only found this one in the SA rules :
SARE_TOCC_BCC_MANY
in the 70_SARE_header0.cf file.
By default, the score is set to 0...

but, I really have problems with false positive !!
(for example mails sent from my serveur, with no address specified in
the bcc field, are tagged with that rule... !)


Then I looked at the SARE file.
There is no real rule to explain what happens :
meta      SARE_TOCC_BCC_MANY       __SARE_HEAD_FALSE
and that's all ! Where is the real rule ?


We also found references to the BCC in the SA Perl source code... but we
did not understand.

I looked on the internet...
Recently, I found that link :
http://mail-archives.apache.org/mod_mbox/spamassassin-commits/200501.mbox/%3C20050116093705.4850.qmail@minotaur.apache.org%3E
Is it a reliable solution or just a test ?


Anyway, being an SMTP relay, exim should be the solution.
But I don't know the settings to do that... !!

Thank by advanced for any help !

Cheers,
