I have a very quick few questions which could probably be answered just as quickly.

Right now I operate a mail relay cluster in front of my main mail/web farm. The relay systems are all running Exim and are configured via ACL's to do a number of anti-spam/malware checks, etc. As of now I operate a pair of application servers for this mail farm that run ClamAV and Spamassassin. The Exim servers pass messages that meet the requirements of the ACL's off to these machines via tcp and return their result back to Exim, etc etc etc. This is all very common practice.

I would like to incorporate DSPAM into the picture and run it from these application servers, or even a dedicated DSPAM server. This is where I have questions. I know the various configuration options DSPAM provides and the one that would fit me best is running it as a stand alone appliance which is fed via LMTP (I believe) and if a SPAM scores above such and such threshold, quarantine it on that server. That is what I envision. Ultimately when a message is quarantined is can be released by the user, at least I'm assuming this capability exists. I would like to have the DSPAM server release the message back to the Exim cluster with a modified header that will in turn feed through one of various manual route routers and to the end destination.

Again, being a newbie to DSPAM, I'm approaching this from a generic standpoint and my experience with similar setups.

Is there anything that I am missing as far as my approach or can anyone offer a good Exim/DSPAM how to that would fit my needs. There used to be an Exim/SA/DSPAM how to on the wiki, but seems I can't get to that anymore.

Thanks much,
James
