I thought of running RBL/LBL agains IPs contained in the last Received headers, but that would also pose a demand for a protocol for LBL/TBL replication between primary and secondary servers. (LBL stands for Local BL, TBL - Temporary BL).

It would?

Here's an example header:

Received: from ([] verified) by (Stalker SMTP Server 1.8b8) with ESMTP id S.0000061073 for <>; Thu, 11 May 2000 02:24:36 -0600
Received: from by (8.8.8+Sun/SMI-SVR4)
        id EAA00299; Thu, 11 May 2000 04:26:24 -0400 (EDT)

OK, now, let's assume for the sake of argument that is an open relay and is not in RBL.  Let's also assume that is 1) a real machine, and 2) is in the RBL.

It would be nice if Sims could be told to check the second received header for an RBL match.  Of course, if there is no second received or if it cannot parse the second received, then it is left to whatever results came in from the first check.

It would also be nice if you could have a separate setting to tell SIMS that if the first received line is a client IP, ignore it and process the mail as if the connection came from the second received line.

It seems to be that this would allow a completely headless/optionless secondary to not open up your primary to all sources of spam.

I'm not seeing anything that would necessitate the secondary knowing _anything_ at all.
