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
