EXIM and SPAM

Hello,

i need some help with exim v.3/v.4 configuration.
My actual configuration looks like this:

Inet --> SPAM_ASSASSIN_MACHINE --> Mail Server (Exchange).

SPAM_ASSASSIN_MACHINE is running Debian with SPAM Proxy Daemon (SpamAssassin
Proxy) which check mail for spam and then send it to mail server.

I would like to add some new features to SPAM_ASSASSIN_MACHINE that it could
do something like this:
(assuming that I have a list of valid Exchange mail addressess in a text
file)

1) if message is marked as SPAM and mail address doesn't exist - delete it
or move to a local folder,
2) if message is marked as SPAM and mail address exist - pass it to the
Exchange mail server,
3) if message is not marked as SPAM and mail address exist - pass it to the
Exchange mail server,
4) if message is not marked as SPAM and mail address doesn't exist - pass it
to the Exchange mail server,

Is it possible to do with Exim and could You help me with this?
Best regards
Marcin

Don't accept mails to nonexistent addresses. If SPAM_ASSASSIN_MACHINE
itself doesn't hold a local user database you can use recipient
verification via smtp callout to your Exchange machine.

Look for the keywords "recipient verification" and "sender
verification" in the exim docs.

Don't use Exim 3.
Exim 4 + Exiscan patch (more or less standard these days) will do a much
better job.

Why not simply reject (never bounce to non local users! [1]) the message.

I would use a reject.
