LinuxQuestions.org - [PostFix] How to set up half-local delivery?

Hi,

I just set up a basic postfix server. It's working halfly... But ;)...

First, what I want to achieve is that postfix checks my local users, resolving them to real emails if needed (based on the aliases file), if they cannot be found locally, it should queue them for delivery and send them out via a relay host.

What I have at this point is this:

Code:

myhostname = my.host.name

alias_maps = hash:/etc/aliases

alias_database = hash:/etc/aliases

myorigin = /etc/mailname

mydestination = localhost, localhost.localdomain, my.host.name, host.name

relayhost = mail.host.name

mynetworks = 127.0.0.0/8

mailbox_command = procmail -a "$EXTENSION"

mailbox_size_limit = 0

recipient_delimiter = +

inet_interfaces = loopback-only



debug_peer_list=127.0.0.1

debug_peer_level=99

What that does is the following:
If I send a mail to myself (echo test | mutt goofy), it will send out a mail to goofy@somedomain.com (where it gets this hostname is a mystery as I cannot find any reference of it within /etc).

Thanks for any explanation!
