For webmail, I use sqwebmail. For imap, I use courier-imap. For MTA
(including virtual domains) I use postfix. For spam, I use
spamassassin. For antivirus I use clamav-milter to interface clamav to postfix.

That's done by spamc, which you can invoke through maildrop, or
procmail. I use maildrop on my server, so I'll describe how to use
that to do what you want.

You need to have postfix pass the message to maildrop. You can either
do this directly in master.cf, or through the .forward mechanism. I
use both, depending on which domain the mail is for. I'll explain how
to do that through .forward, since that's simpler

In the user's $HOME/.forward file, you want to have something like:


|/usr/bin/maildrop


Now, you want to create a $HOME/.mailfilter file, which should look
something like:


DEFAULT="$HOME/Maildir/"

xfilter "/usr/bin/spamc"
if (/^X-Spam-Flag: YES/:h || /^X-Spam-Status: Yes/:h)
{
  to "$DEFAULT/.Spam/"
}


If the message is ham, it goes to $HOME/Maildir/. If the message is
spam, it goes to $HOME/Maildir/.Spam/ This assumes you are using the
Maildir mailbox format, which I am.
