So what you are saying is that the x-spam-status headers are not present when email goes through normally or when they are run manually? Can you paste your amavis config here? From: Gabriele Bulfon [mailto:gabriele.bul...@sonicle.com] Sent: Tuesday, June 27, 2017 9:03 AM To: Dino Edwards ; amavis-users@amavis.org Subject: [SUSPECTED SPAM]RE: different spamassassin behaviours The x-spam-status headers on that cases are not present, because the score is too low, and is considered non-spam. Is there any way I can force the injection of the x-spam-status header even for low scores? This may help. I meant that all the cf files (the rules files) are taken from the same place by spamassassin, both manually and automatically during postfix injection, as I can see it from the spam taken. And finally, yes, I can find the logs you say, where the mail (that manually scores 18.0+) passes as "CLEAN" in amavis and back into postfix. I attach an example email, and here is the relative log while passing in: Jun 27 14:30:15 cloudserver amavis[28190]: [ID 702911 mail.notice] (28190-16) Passed CLEAN, [107.175.149.43] [107.175.149.43] vivint.premier-provi...@tmess.us - davide.dicos...@eurovetrocap.com , Message-ID: 037996f410ef6dcfefa9bbb8b98e2681.3964721.19453093@tmess.us_ys9 , mail_id: tW7q84X98Ieq, Hits: -0.347, size: 5698, queued_as: 9C78D27B16D, 1781 ms ------------------------------------------------------------------------------------------- Sonicle S.r.l. : http://www.sonicle.com Music: http://www.gabrielebulfon.com Quantum Mechanics : http://www.cdbaby.com/cd/gabrielebulfon ---------------------------------------------------------------------------------- Da: Dino Edwards dino.edwa...@mydirectmail.net A: amavis-users@amavis.org Data: 27 giugno 2017 13.59.37 CEST Oggetto: RE: different spamassassin behaviours Can you provide the x-spam-status headers for the same email when run through Postfix normally and then manually so we can see the differences? Also, I'm a little confused, what do you mean when you say " All the files are taken from /sonicle/etc/mail/spamassassin and /sonicle/share/spamassassin"? Also, in your mail log, do you say a lines similar to below? The first one is Amavis passing the message as CLEAN and then re-injecting it back to Postfix on port 10025 for delivery.

On my installations, amavisd runs under the "snclamav" user, while the smtp-amavis postfix daemons run under the "snclmail" user. I run the bayes learn using the snclamav user, and also run spamassassin debug mode using the same user, that stores the bayes database in a specific path. Any idea what may happen in amavisd spawn spamassassin that does not happen in manual debug mode?
