For my new-ish install, I’ve noticed a couple symbols were flagging legit ham as spam. So far here is my list of changes:
- Changed FREEMAIL_POLICY_FAILURE from 16 to 4
- Changed BAYES_SPAM from 4.50 to 8
- Changed BAYES_HAM from -5.50 to -9
- Changed FUZZY_DENIED from 12 to 0
- Changed PH_SURBL_MULTI from 7.5 to 3
- Changed URIBL_GREY from 2.5 to 0
The two biggest offenders are FUZZY_DENIED and FREEMAIL_POLICY_FAILURE - these were way too extreme for my emails. I’ve also noticed PH_SURBL_MULTI was causing some issues too.
I’m trying to learn more weight onto the bayes output, as this seems to be more accurate.
My questions are:
- Who else has made similar symbol changes? Are any of my changes common or is there a hidden danger in these?
- What other symbol changes have you made or are common in a new setup.
Thanks.
