Re: Howto Per-User spamassassin with postfix-LDAP?

[Theodore Knab <tjk@annapolislinux.org>]

It all depends on how much of a load you want to put on your mail server. ;-)

Spam-Assassin can be run per user as long as some filtering language calls SPAM assassin first.

Both procmail and mailfilter can do this.

A mailfilter example would look like this:

import SENDER
import RECIPIENT
import HOME
MAILBOX="$HOME/Maildir"
#filename: $HOME/.mailfilter
#if message size is less than 26K scan it 
if ($SIZE < 26144)
{
        exception {
                #SPAM assassin ready
                xfilter "/usr/bin/spamassassin"

		#if you want to run spamd on your server
		#this program lets you call the daemon safely
                #xfilter "/usr/bin/spamc"
        }

}
#if the message is tagged as spam put it into the SPAM MAILBOX
#otherwise   ***LEAVE IT ALONE FOR THE LOCAL CONFIG TO DELIVER***
if (/^X-Spam-Flag: *YES/)
{
        exception {
                #to spamfolder
                to "$DEFAULT/.Spam/"
        }
} 

Postfix needs to have a local delivery agent for this to work.

Either maildrop,local,and lmtp should work.

For example, I am using the following postfix delivery agent:
local_transport = lmtp
