I have a rather odd requirement specifically initially dealing with sendmail
but which may have other applications.
In this particular case, we have an interface on the firewall which has 2 IP
addresses assigned to it. The route from us to our destination uses this
interface. We would like to be able to have sendmail send, on a message by
message basis, use one or the other IP address and the source; that is, on
selected messages, we want to use an IP/interface other than the one that
the routing algorithm would normally select. A similar application would be
to have sendmail, or another application, send through another interface
instead of using the one that the default route is on. To add further
complication, we may wish to send mail to the same host but have them leave
with different source IPs. All IP addresses are ours and appropriately
registered in DNS.
I believe this is really a network layer issue, not really an application
issue.
"Sendmail" is our current application- we may wish to do this on other
applications (ex: FTP) down the road.
