[Techtalk] Postfix and ODMR

And the answer is...

1. edit /etc/postfix/virtual and add virtual domains for the odmr domains.

	example.com	ODMR #the second field can be anything
	postmaster at example.com	postmaster #Standard postmaster forwarding
	first.last at example.com	user #Individual address rewrites.

	example2.com	ODMR #A second virtual domain
	...

add the following line to /etc/postfix/main.cf

virtual_maps = hash:/etc/postfix/virtual


The crucial thing that left postfix hanging was that I forgot to run

postmap /etc/postfix/virtual

Once I ran that, my new domains were picked up and all seems to work...
