Hello,
postfix communicates with spamassassin via a milter: # milter settings (for DKIM, spam filters,...) smtpd_milters = unix:/opendkim/opendkim.sock,local:spamass/spamass.sock non_smtpd_milters = $smtpd_milters As said, I can see logs in mail.log that show messages being processed and correctly identified as spam/ham. Example from a few minutes ago: Nov 26 12:45:06 bollu spamd[30993]: learn: auto-learn: adding head_only points 0.01 Nov 26 12:45:06 bollu spamd[30993]: learn: auto-learn: message score: 3.264, computed score for autolearn: 3.337 Nov 26 12:45:06 bollu spamd[30993]: learn: auto-learn? ham=0.1, spam=12, body-points=1.911, head-points=1.425, learned-points=0.8 Nov 26 12:45:06 bollu spamd[30993]: learn: auto-learn? no: inside auto-learn thresholds, not considered ham or spam Nov 26 12:45:06 bollu spamd[30993]: check: is spam? score=3.264 required=5 Nov 26 12:45:06 bollu spamd[30993]: check: tests=BAYES_50,FSL_HELO_NON_FQDN_1,HTML_IMAGE_RATIO_02,HTML_MESSAGE,MIME_HTML_ONLY,MIME_QP_LONG_LINE,MISSING_MID,RDNS_NONE,SPF_PASS,T_REMOTE_IMAGE,UNPARSEABLE_RELAY,URIBL_BLOCKED Nov 26 12:45:06 bollu spamd[30993]: check: subtests=__ANY_TEXT_ATTACH,__ANY_TEXT_ATTACH_DOC,__BODY_TEXT_LINE,__BODY_TEXT_LINE,__BODY_TEXT_LINE,__BUGGED_IMG,__COMMENT_EXISTS,__CT,__CTE,__CTYPE_HTML,__DKIM_DEPENDABLE,__DOS_BODY_FRI,__DOS_DIRECT_TO_MX,__DOS_HAS_ANY_URI,__DOS_RCVD_FRI,__DOS_REF_TODAY,__DOS_SINGLE_EXT_RELAY,__ENV_AND_HDR_FROM_MATCH,__FB_NUM_PERCNT,__FROM_FULL_NAME,__HAS_ANY_URI,__HAS_DATE,__HAS_FROM,__HAS_RCVD,__HAS_SUBJECT,__HAS_TO,__HAS_URI,__HELO_NO_DOMAIN,__HTML_LINK_IMAGE,__LAST_EXTERNAL_RELAY_NO_AUTH,__LAST_UNTRUSTED_RELAY_NO_AUTH,__LCL__ENV_AND_HDR_FROM_MATCH,__LOCAL_PP_NONPPURL,__MAIL_LINK,__MIME_HTML,__MIME_VERSION,__MISSING_REF,__MISSING_REPLY,__NAKED_TO,__NONEMPTY_BODY,__NOT_A_PERSON,__NOT_SPOOFED,__NUMBERS_IN_SUBJ,__RDNS_NONE,__REMOTE_IMAGE,__STY_INVIS,__SUBJ_NOT_SHORT,__TAG_EXISTS_BODY,__TAG_EXISTS_HEAD,__TAG_EXISTS_HTML,__TOCC_EXISTS,__TO_NO_ARROWS_R,__TO_NO_BRKTS_HTML_ONLY,__TO_NO_BRKTS_NORDNS_HTML,__TO_NO_BRKTS_PCNT,__UNPARSEABLE_RELAY_COUNT,__UNSUB_LINK,__URI_12LTRDOM Nov 26 12:45:06 bollu spamd[30993]: spamd: clean message (3.3/5.0) for cyrpub:65534 in 0.3 seconds, 9763 bytes.
