I hope I can get some help with the router configuration. This
configuration worked for previous versions of exim but not with the current
one.
I have been working on it for the past two weeks since updating the mail
server and have no success in finding more information of examples with
sender_address, sender_address_domains that I could work with.
The purpose of the router would be to send a copy of the email if a
forwarder with the suffix archive. (e.g.: archive.user@???) is
present in the domain's aliases file (e.g.: etc/valiases/domain.tld).
