This is a problem with the exchange config I think. You'd be best having
exchange setup on its normal ports and using cache_peer in squid to do
the routing in the background.

cache_peer yet again. Its really a very powerful tool for routing
requests to different servers and ports without making any of it visible
to the users.

Given that you have such a complicated back-end server setup I think you
will be needing to read over the cache_peer and cache_peer_access and
ACL config details.

http://www.squid-cache.org/Versions/v2/2.6/cfgman/cache_peer.html
http://www.squid-cache.org/Versions/v2/2.6/cfgman/cache_peer_access.html
http://www.squid-cache.org/Versions/v2/2.6/cfgman/acl.html
and a tutorial on usage:
http://wiki.squid-cache.org/SquidFaq/SquidAcl

(I assume you are using 2.6, since its the most common, for the other
versions just tweak the URI)
