Greetings - I guess you can do it in either…
- In Exim it's easy: you would rewrite the address(es) from the old domain to the new one. Read the chapter on rewriting in the *Exim Specification*. - In Dovecot I guess you'd just modify the *password_query* construct to see if the *domain* was either the old or new domain. Something to think about is the effect of secretly rewriting the old domain to new domain in addresses. If you do then, depending which address(es) you rewrite, recipients might not be able to tell whether someone sent to the old domain name or the new one, so can't tell the sender to start using their new address instead. It depends on whether you plan to run both domains indefinitely, or want to phase the old one out eventually.
