My rimu host hosts a number of domains, including,, and 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.

1 /etc/postfix/
2     virtual_alias_domains = ...other hosted domains...
3     virtual_alias_maps = hash:/etc/postfix/virtual
5 /etc/postfix/virtual:
6 postmaster
7        joe@somewhere
8       jane@somewhere-else
9     # Uncomment entry below to implement a catch-all address
10     #         jim@yet-another-site
11     ...virtual aliases for more domains...

Presto, instant email!
