postfix, procmail, cyrus
 

Is anyone using postfix, procmail, and cyrus on their mail server? I am running Mandrake 10. Cyrus works; I can login and see folders. Postfix works; I can send mail locally(not to cyrus). But when I try to plug procmail into the mix I get error in my mail log and delivery fails. Theoretically this setup should work but most of the documentation is out of date or does not work. Does anyone have this working? I am using:

- postfix-2.1.1-0.1.100mdk
- procmail-3.22-4mdk
- cyrus-imapd-utils-2.1.16-5mdk
- cyrus-sasl-2.1.15-10mdk
- cyrus-imapd-2.1.16-5mdk

Eventually I want to use procmail to run mail through spamassassin and some virus scanner.
