Mailing List Archive: add routing to external MX

Dear exim-dev@exim.org<mailto:exim-dev@exim.org> team,

My problem is that exim.conf does not offer to properly route external MX. Local delivery may be wrong.

* When a domain is created to be moved while testing and setting up:
Mail from another domain on the shared server goes to the preparated site unable to receive mail.

* When a domain has MS Exchange:
originaldomain.com -> forwardingdomain.com (exists on same shared server)-> externalmxdomain.com returns with No such recipient here.

You can also read my web page https://webhostingtech.nl/monitoring-email/solve-exim-issues/

Proposed for exim.conf:
domainlist external_mx_domains = lsearch;/etc/virtual/external_mx_domains
routing: domains = +external_mx_domains : ! +local_domains

Kind regards
Jan Willem Stegink

What you decide is right for your Exim configuration file is up to you.
There's no change implied in the Exim codebase.
That's why the configuration is a file.
