I have found Spamassassin, but what I have read it is difficult to get it working with cyrus + sendmail, since it uses procmail?!   Is there anyone out there having som experience or knowledge about this issue?   Regards   Henrik I do not recommend the use of procmail for this purpose because your mail delivery will get very CPU and memory expensive and so, in most cases, very slow. As explained by Craig it's up to the MTA to scan for spam. Personally, i prefer Postfix-Amavis-Cyrus: Postfix gives the received mail to Amavis which starts (in my case) at first a virus-scanner and then spamassassin. If a virus was found the mail delivery is stopped. If it is spam a Header-Tag will be added (X-Spam-Level). Amavis gives the mail back to Posfix that will deliver local mail to Cyrus. Sieve is now started and checks whether the mail has a Header-Tag named X-Spam-Level and if true the message will be put in the INBOX.Junk folder. Greetings, Marek
