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 i开发者_开发知识库s 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.
You should create 2 routers and 2 transports, below configuration could work.
domain_list my_relay_2500 = example1.com:example2.com
domain_list my_relay_2501 = example3.com:example4.com
my_relay_2500_router:
driver = manualroute
domains = +my_relay_2500
transport = my_remote_smtp_2500
route_data = ${lookup{$domain}lsearch{/etc/exim/remote_relay.txt}}
no_more
# after `begin transports`
my_remote_smtp_2500:
driver: smtp
port: 2500
my_remote_smtp_2501:
driver: smtp
port: 2501
File /etc/exim/remote_relay.txt
example1.com: 10.0.0.3 my_remote_smtp_2500
example2.com: 10.0.0.3 my_remote_smtp_2500
example3.com: 10.0.0.3 my_remote_smtp_2501
example4.com: 10.0.0.3 my_remote_smtp_2501
