Running email in dn42 is not very complicated. Your SMTP daemon probably already listens on the wildcard address, so you mostly need to:
By default on Debian, Exim refuses to send mail to other mailservers when they resolve to RFC1918 addresses. This will manifest by the following error message when trying to send a mail:
** foo@bar.dn42: all relevant MX records point to non-existent hosts
This is controlled by the ignore_target_hosts
variable in the configuration file.
Don't forget to add your dn42 domains to the list of local domains, so that you accept incoming emails. On Debian, it is controlled by dc_other_hostnames
in update-exim4.conf.conf
. For instance:
dc_other_hostnames='myself.org;myself.dn42;myserver.myself.dn42'
