Can Exchange control what IP address mail goes out on

[RichRWH]

Is there any way to control what IP address Exchange 5.5 will use when sending mail? Our company has a pool of Ip's
but only one will correctly resolve to our domain name
when doing a reverse dns lookup. This means some of our
outgoing mail gets rejected. Some of our customers use AOL
and they do not always get our mail. I am not sure if
this is a router, dns or exchange issue (or all 3).

Rich, You probably have a firewall or some sort of NAT device that will handle this for you. That is the place to control what the outside world sees as far as IP adresses are concerned.
