My rimu host hosts a number of domains, including oroup.com, openrelay.com, cadabraco.com and drugmaps.com. I want to be able to send and receive email to those domains, but (at least for now) I don’t really want to set up dovecot locally and actually deal with mail. So the ideal thing is just to forward your mail to another email address. Postfix is a little daunting at first, but the key instructions turn out to be quite simple.
