I have never used a Foundry Load Balancer so my response may be way off. I
am assuming it is not functioning as a MTA, but is simply rewriting the
source IP portion of packets.

If the source IP of incoming packets destined to your declude gateways is
replaced with that of your load balancer, it does not constitute an
additional hop as far as declude is concerned. The message header will
likely report the connecting IP address (in this case, being that of your
load balancer if doing source NAT) but also with the sending MTA's HELO.

The IP tests including RBL lookups and SPF checks are based on the last
reported sending MTA's IP address. Also, other DNS tests such as REVDNS
won't mean much of anything anymore since declude will only be checking for
a PTR for the IP of your load balancer. Non-IP based tests should work fine
I would think.

As much of a pain as it might be, I would stick with DSR if you don't want
to lose declude's IP-based tests.
