All I see in the headers of the message you posted are spamassassin results. The scores for each failed test sum up to something far below the default threshold score of 5.0. It therefore passes the spamassassin check.
Spamassassin further indicates that the SPF failure is temporary and scores it a zero. We have absolutely no information, at least that I saw, about how those other programs and protocols should cause any of them to reject the message. It seems to me this is only partly a postfix problem (via postscreen, which is why others are asking about it). Sadly, no matter what you do, some spam will always get through. The war on spam is ongoing with each side continuing to develop in an attempt to evade their opponents' efforts. It will probably never be won, at least with SMTP. -- David Benfell, Ph.D. benf...@parts-unknown.org
