4.71 has a some bugs related to multiple outbound ip addresses. the
work-around I used was to decide in the router which IP address to use
for delivery and to have one transport for each IP address, but in the
trasports to still use a string expansion on the IP address.
The multiplicity of transports stops queued emails from departing
through the wrong IP address, The string expansion keeps the retry
databases for each ip address from interacting.
As I understand it these bugs have been fixed in the laest version.
