legitimate email getting marked as spam... Tuning advice

[Rick Bragg]

Hi, 

I am a bit of a newbe at all this, so any help will be very appreciated!

I have a seemingly good working install of MailScanner, sendmail,
spamassassin, squirrelmail, and clambAV.  I am delivering and accepting
mail for a dozen or so of my "clients" domains.  It seems that most of
my clients email that they send me gets marked as spam in my in-box.  I
did not do anything with the bayes database yet, and I'm not sure where
to start.  Is there a way that I can "tune" the system on a system-wide
level? and/or do each of my clients have to tune their own?  If so, how
do they do that?  I am personally using evolution, some of my clients
use squirrelmail, some use thunderbird etc...  Can my clients tune their
spam database via their mailer software? 

I would basically like to know:
Is there is a way to tune spamassassin on a system-wide level for all my
domains at once?
And:
What is the best way for each of my clients to go about tuning their own
settings? (or me doing if for them)

Thanks
Rick Bragg

p.s.
Take care Jules, take a nice holiday, maybe try lots of milk-thistle in
the meantime, you will get through this!
