Problems with false positives
Hello everyone,
Something weird is happenning with my spamassassin, you see. almost all of
the users on my server are on an email notification system, so all of them
receive the same message from the same address, it's ok and i even
withelisted the address, the problem is that even then I'm getting some
false positives, so of the 2000 mails, a significant portion (around 200)
get classified as spam. Also none of my users has personal rules, so
everything is filtered by my server.
So why does spamassassin classifies some mails even though it's exactly the
same message for all the addresses?
thank you very much

per-user bayes, perhaps?
Can you post the headers from a message that was scored as spam and
from a message that was scored as ham so that we can compare?
