[EMAIL PROTECTED] admin]$ rpm -qa | grep -i postfix postfix-1.1.11-11 I guess I need to go look at 2.0.12 and see what it offers. I do not know what version is in rawhide.

I really did not want to configure Postfix to do the filtering; I really like the job done by SA. Also, IIUC, reject essentially says nobody home, go away, whereas bounce says we are here but do not want to talk to you? Quarantine says the mail accepted for an inbox, but it actually goes to a junk directory. It is the manual maintenance of the junk directory that is starting to be a time waste. > However, the current Postfix snapshot smtpd can be configured to > hang onto the client connection until Amavis-d has scanned the > message.

That is exactly what I have in mind. Use Amavis-d to scan with SA and maybe AV, then reject on that basis as opposed to bounce or quarantine.

When you say "smtpd reject high-score spam," was that via the built-in Postfix test hooks or using a different method (a different MTA with SA - such as sendmail)? Based on that experience, it might not seem worth the time to configure things to do it. On-the-other-hand, it does remove the need to review manually the quarantined mail. Valid mail gets through. Invalid mail goes back with a reject (with a potential of a small error rate of rejecting valid as invalid). > You don't have to dev-null spam with Amavis-d/SA-Exim, you can > quarantine it in a dedicated directory. That's what I do. That is how I use SA now via spamc/procmail. The downside is I have to go through the directory manually to check what is there. I was trying to find a way to not even look at the junk, but still send a reject message in case of a valid message being tagged. Does Exim provide any benefits over Postfix? I am pretty comfortable with Postfix. How complicated is the switch from it to Exim? Have you had any success with the current snapshot of Postfix with regard to this issue? Thank you for your help.
