Previously you indicated that you had 755293 ham trained (from 788787-33494). Unless you have an extreme number of FPs your training is mostly from auto-learning. > in dovecot/conf.d/90-plugin.conf i have > plugin { ... > antispam_signature = X-DSPAM-Signature ... > training antispam_signature_missing = error This looks wrong, you are checking for a DSPAM signature, and then training SpamAssassin. Possibly this is preventing the plug-in from working, if it's treating the absence of the header as an error. I'm not keen on using that plugin with SA as it trains only based on full misclassifications which can (or should) lead to a very low rate of ham training.
