I'm sure it can't be a misconfiguration of spampd or Spamassassin, since Postfix just doesn't relay these mails to spampd, so the error must be at Posfix: May 26 14:04:48 mail postfix/smtpd[18487]: connect from 220-143-62-59.dynamic.hinet.net[220.143.62.59] May 26 14:04:49 mail postfix/smtpd[18487]: setting up TLS connection from 220-143-62-59.dynamic.hinet.net[220.143.62.59] May 26 14:04:50 mail postfix/smtpd[18487]: Anonymous TLS connection established from 220-143-62-59.dynamic.hinet.net[220.143.62.59]: TLSv1 with cipher RC4-MD5 (128/128 bits) May 26 14:04:51 mail postfix/smtpd[18487]: CB46FD60008: client=220-143-62-59.dynamic.hinet.net[220.143.62.59] May 26 14:04:53 mail postfix/cleanup[18188]: CB46FD60008: message-id=<> May 26 14:04:53 mail postfix/qmgr[18055]: CB46FD60008: from=<canad...@yahoo.com>, size=717, nrcpt=1 (queue active) May 26 14:04:53 mail postfix/virtual[18464]: CB46FD60008: to=<x...@xxxxxxx.xx>, orig_to=<xxxxxxxx...@xxxxxxx.xx>, relay=virtual, delay=2.1, delays=2.1/0/0/0.01, dsn=2.0.0, status=sent (delivered to maildir) May 26 14:04:53 mail postfix/qmgr[18055]: CB46FD60008: removed May 26 14:04:54 mail postfix/smtpd[18487]: lost connection after RSET from 220-143-62-59.dynamic.hinet.net[220.143.62.59] May 26 14:04:54 mail postfix/smtpd[18487]: disconnect from 220-143-62-59.dynamic.hinet.net[220.143.62.59] > didn't check all your samples, but as for hinet, if you "have no hope > from them", then firewall them: Sure, I could block them with Postfix, a RBL would be enough. But I wonder why they are not relayed properly (It really happens only at exactly these messages [http://pastebin.com/4arTzeRu], less than at 1 of 100.000). After several hours of research there are only two possibilities: Either I made a weird mistake and have overseen something or there is a bug somewhere. Jan-Kaspar
