Spamassassin 3 and postfix

[mailinglists]

hi, i use postfix and amavisd-new/spamassassin to fight our spam. We are very happy with this setup. It works great. We only have one problem. Sending mail with a Emailclient from our dialup account at home to another mailbox hosted by our server causes Spmassassin to mark that email as spam! Here are the tests: HTML_90_100, HTML_MESSAGE, MIME_HTML_MOSTLY, RCVD_IN_DSBL, RCVD_IN_NJABL_DUL, RCVD_IN_SORBS_DUL   Our problem is, that Spamassassin (plus razor and pyzor) check the Email also if the user was Sasl authenticated. And our provider is listed in many DSBL lists. Is there any trick to tell amavisd to NOT scan emails from sasl authenticated clients. Or is postfix able to NOT filter sasl authenticate emails?   thx Florian Engelmann
