Asked this on StackOverflow (http://stackoverflow.com/questions/1655281/exim4-nonstandard-ports) but someone pointed out it belongs here.
I am trying to use exim4 on debian to relay mail, nothing more. I have a stage mail server and a production mail server (both written custom in python to do weird stuff). I also have all these running on a single linode host.
production mail is on port 2500, stage mail is running on port 2501. I'd like exim to relay mail based on the target domain to these nonstandard ports. I can easily get it to recognize the domain, but I can't seem to find any info on how to add port information to the configuration.
