Spamassassin uses a scoring system, so there could be any number of reasons that the message is listed as spam, of which blacklists are only a small part. > My doubt is for what reason these mail are blocked ? Change your logging level to 2 in amavisd.conf so that you log the SPAM-TAG messages: Jun 23 11:16:50 ca amavis[18393]: (18393-14) SPAM-TAG, -> , No, score=3.823 tagged_above=-99 required=4.5 tests=[FUZZY_AMBIEN=1.851, HTML_MESSAGE=0.001, HTML_TITLE_SUBJ_DIFF=2.171, L_P0F_Unix=-1, MIME_HEADER_CTYPE_ONLY=1.996, MIME_HTML_ONLY=1.105, RCVD_IN_DNSWL_MED=-2.3, RELAY_US=0.01, SPF_PASS=-0.001, T_RP_MATCHES_RCVD=-0.01] autolearn=disabled > On my mail server I have SA-3.2.5 with postfix/amavisd-new/clamav. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281

Why do you think this si SpamAssassin problem? Nothing in this log file indicates so. Check other log files and postfix configuration. Since you are running amavis, check amavis configuration too. I doubt SA has anything to do with this. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.

Mail discarded
Hi, from a few days much incomings mails are blocked and in log file I have always 'discarded, UBE': Jun 24 13:10:23 mail postfix/qmgr[445]: CB6FD26A1AF: from=, size=49182, nrcpt=1 (queue active) Jun 24 13:10:26 mail postfix/smtp[25251]: CB6FD26A1AF: to=, orig_to=y...@mydomain.com, relay=127.0.0.1[127.0.0.1]:10024, delay=4.2, delays=1.3/0/0.01/2.9, dsn=2.7.1, status=sent (250 2.7.1 Ok, discarded, UBE, id=23600-10) Jun 24 13:10:26 mail postfix/qmgr[445]: CB6FD26A1AF: removed but the domain 'email.it' (but I have this problem with much mail domains) isn't in blacklist and this domain is certainly 'clean'. My doubt is for what reason these mail are blocked ? On my mail server I have SA-3.2.5 with postfix/amavisd-new/clamav. Thanks. -- Salvatore.

The mail is not necessarily discarded however, it may have been quarantined by amavisd-new. Of course this all depends on settings in amavisd-new. The first message shows the amavisd-new log entry where spamassassin scored Hits: 4.339 and this message was Passed CLEAN. You do not show the amavisd-new log entry for the second message. If the message has only this small amout of text it it, this seems like a pretty high score, so you do need to see which rules hit. If you increase amavisd-new $log_level to 2 during testing, you should see which rules were triggered. Here is a sample from amavisd-new 2.6.4: # tail -f /var/log/mail.log | grep SPAM May 23 02:55:54 filter amavis[3942]: (03942-01) SPAM-TAG, -> , No, score=1.317 required=6.1 tests=[ALL_TRUSTED=-1, AWL=0.549, DATE_IN_FUTURE_06_12=0.001, MISSING_SUBJECT=1.767] autolearn=no -- Gary V

It merely classifies it, any action is left to other tools in your chain. You just clearly showed that it is postfix discarding the mail. What's missing from your pasted logs is the reason *why* postfix did that. You'll need to dig deeper. > postfix 2.5.6 > amavisd-new > spamassassin > clamav So, first question to check for in the logs is, which of these tools even processed the message, and what the respective results are. -- char *t="\10pse\0r\0dtu...@ghno\x4e\xc8\x79\xf4\xab\x51\x8a\x10\xf4\xf4\xc4"; main(){ char h,m=h=*t++,*x=t+2*h,c,i,l=*x,s=0; for (i=0;i>=1)||!t[s+h]){ putchar(t[s]);h=m;s=0; }}}
