My rimu host hosts a number of domains, including [oroup.com](http://oroup.com/?ref=oroup.com), [openrelay.com](http://openrelay.com/?ref=oroup.com), [cadabraco.com](http://cadabraco.com/?ref=oroup.com) and [drugmaps.com](http://www.drugmaps.com/?ref=oroup.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](http://www.postfix.org/VIRTUAL%5FREADME.html?ref=oroup.com#forwarding) turn out to be quite simple.

Presto, instant email!
