[exim] Setting Outbound Interfaces

Hi all,

First off thanks to everyone on the list who assisted me in getting greg
listing working, and for all the other tidbits getting my ACLs up to snuff.

My next adverture is to get the ip address mappings up to snuff. That is, to
get outgoing mail to be sent through the ip address assigned for whatever
domain.

With the Routers and Transports below, I am seeing a few glitches. The fist
two are the problems with gmail and aol - they are returning multiple ip
addresses. That asside, I dont think I should be seening logs like this at
all.

Question one: Can anyone see whats wronge with my remote_smtp_alias
Transport?
