Sounds like you want to use "Razor2" which you can as part of SpamAssassin.
This system uses checksums of messages that are known to be spam, and
stores the checksums on central servers. Every time you receive a message
it checks it against the known spam checksums and uses that to decide if it
is spam or not.

Look at http://razor.sourceforge.net/ (I think) and you should find lots
more about Razor and Razor2.

Also, using the new Bayes engine in SpamAssassin 2.51 (but I would advise
you to wait for 2.52 release), the anti-spam engine will learn about spam
messages that it got wrong by your users feeding back the spam into the
engine. I have 2 addresses here, "spam" and "notspam", which users bounce
mail to when the spam engine gets it wrong. So its performance improves
with time as it learns lots of new spam.

You can let your users set their own preferences by using rulesets in the
MailScanner.conf file. Take a look in /etc/MailScanner/rules for some brief
instructions and examples. This can all, for example, be linked to a
database containing all the users' preferences.
