I'm looking into setting up a client who has two domain names, one established another just registered.
The established domain name would only have its MX records changed so that email can be sent to our servers under the new domain name.
If someone was to send email to email@example.com
can this then be placed in the mailbox for firstname.lastname@example.org
, keeping in mind that we do not manage the zone for domain1.com, nor host this domain name on our servers, they only want to direct mail going to domain1.com to domain2.com.
Is this possible with a standard exim setup?
