sa-learn with an Exchange server

[Raymond Jette]

Thanks. Will the /etc/mail/spamassassin directory be replaced during an
upgrade?

Raymond,

 

all files ending in .cf located in /etc/mail/spamassassin are used by
SpamAssassin. Of course you could put custom rules into
/etc/MailScanner/spam.assassin.prefs.conf too, but I would not recommend
to do so. Please keep in mind to do a test after implementing new rules.

 

 

Regards,

Roland

Thanks for the link. I'll take a look at this. I am in the process of
fighting spam in only one place. I just implemented Postfix, MS,
SpamAssassin a few months ago. I'm still in the process of removing IMF.


 

You're right about all of the false positives. 

 

I host mail for 37 domains. I receive a lot of spam still (not as much
as before) and I'm always looking for more ways to improve the system.

 

Where is the correct location to put custom SA rules? I have read
/etc/mail/SpamAssassin. Is this correct even when running MS? Does
anyone have any good links on creating custom rules?

 

Thanks,

Ray

You should fight spam at one place only. The spam detection included in
Exchange 2003/2007 is not very reliable, as it produces many false
positives. See my last mail, this should give you a hint.

I also have thousands of spam messages that IMF is removing on my
Exchange server. Is there a way to have SpamAssassin learn these
messages?

Good morning,

What is the best way to do an sa-learn when with an Exchange server? I
have a spam mailbox  were users have been forwarding spam. The problem
is that they forwarded the mail so the message headers have changed.  Is
there a way to remove local headers from my mail systems or will I have
to do this by hand?

 

Thanks for the help,

Ray
