Ubuntu – Forward email from exim to another mail server on different port

eximUbuntu

Exim seems to be very flexible and configurable. What would be the best approach for me to forward an incoming email to exim to another mail server running on a different port like lamson? I am running exim and lamson on the same ubuntu machine.

Thanks heaps.

You need a manualroute router to point to the appropriate transport, where you override the standard port. Something like (untested):

begin routers

lamson_host_relay:
    driver = manualroute
    route_list = * lamson.server.com byname
    transport = lamson_smtp

begin transports

lamson_smtp:
    driver = smtp
    port = 666

How to Set Up Exim to Forward Mail

You will need to use a redirect router. Read the Exim Router specification, as it can do many things and thus can get quite complex.

Basically, you will need to set something up like this (untested)


sender_redirect:
  driver = redirect
  data = ${lookup{$sender_address}lsearch{/etc/exim4/sender_redirects}}

Then create a file in /etc/exim4/sender_redirects that contains the redirects in a line-separated colon-delimited format, like this:


me@example.com: me@gmail.com

You could use the After-Queue Content Filter feature: http://www.postfix.org/FILTER_README.html

The readme file contains an example of a very simple filter shell script. You could start with that example and build your own script.
