hi, I had a mail relay running postfix (well, actually I still have), lying in front of my exchange server, so all mail sent to outside, goes through this postfix.
I got a link on security-basics that describes an installation of postfix-amavisd-spamassassin to filter spam. I've followed Scott L. Henderson's step-by-step doc (http://www.geocities.com/scottlhenderson/spamfilter.html), and also a razor2 configuration (http://www.dambrosioauto.com/razor_config.html), and everything is working really smoothly. but I still have a few doubts... 1- a few messages are not beeing tagged as a spam, and so, a few users are still getting unsolicited mails and complaining a lot! even the amount of spam had been decreased (1 of the users has recieved only 5 spams since last night... he used to recieve almost a 100 spams a day). I told all the users to forward the spams to me, and I would do something about it (yeah... I'm doing! I'm asking for help...). all the messages look like spam to me (subject and body). how should I block these messages. I've been adding the most common subject lines to postfix' header_checks file, but that seems pretty stupid to me. 2- sometimes, when I have a few rules on header_checks file (like the ones above): ## Anonymous?? ## /^(To|Cc): $/ REJECT Mail detected as spam - Specify recipients /^(To|Cc): undisclosed-recipients/ REJECT Mail detected as spam - Specify recipients ## Known spam ## /^X-Spam-Level: \*\*\*\*\*\*\*\*/ REJECT Mail detected as spam ... I get something really weird on the log file: May 31 15:19:03 mx amavis[30362]: (30362-02) mail_via_smtp: 550 5.6.0 Failed, id=30362-02, from MTA: 550 Error: Mail detected as spam - Specify recipients May 31 15:19:03 mx amavis[30362]: (30362-02) TROUBLE in check_mail: spam quar+notif FAILED: Can not quarantine: 550 5.6.0 Failed, id=30362-02, from MTA: 550 Error: Mail detected as spam - Specify recipients at /usr/local/sbin/amavisd line 6038, <GEN6> line 448.

(in reply to end of DATA command)) 3- I read somewhere about DCC and Pyzor. I've configured it to use only Razor2, should I install these other couple tools?
