Goal

What alternatives are there to randomize client IP address on outbound connections?

If an MTA system has multiple interfaces available, it would normally be up to the TCP/IP layers to pick the source IP address on outbound connections. The interfaceaddress channel option allows the specification of a single source IP.
That would be great if there was only one IP we want to use as the source address. But, what if we wanted the source address to round-robin (or otherwise randomize) between a list of client addresses...

Currently the only way to do that would be to define a channel per IP address and use rewrite rules to spread the traffic across those.
