Hello! I've searched the forum and it seems like many have asked the question but the answers are few. We have an SMTP-GW in front of our plesk server wich do antivirus and spam filtering. This works just fine so we don't want to run SA and A/V on the plesk server. The problem comes when the users shall filter out the spam. Our SPAM-GW adds X-spam-level: **** where the amount of * depends on the score SA gives the mail. This is nice because people can choose to filter the spam on different levels. In our present environment the do this via procmail, but how can we do this in our plesk environment? In horde and squirrelmail you can enable filters, but I guess this only applies when you use the webmail and not when you use IMAP. Is there any way to filter the mails serverwide so that it doesn't matter if you use IMAP, webmail or redirect them to another address?
