If I have a domain in the virtual map,

virtual_maps = hash:/etc/postfix/virtual

and it does not have a

example.com anything

line, but instead only has

userexample.com userexample.com, otheruserexample.com
user2example.com user2local.domain

(It is not a mistake that the two domains are the same in the first line.)

And then I have an entry like

example.com :mail.example.com

In transports, where mail is a host that will process most of the mail for
mail.example.com, will my machine accept mail from untrusted hosts for
userexample.com and relay it using the transports entry? I have
$virtual_maps in relay_domains. The man page is not clear on whether or
not I need to have the "anything" line for it to relay for untrusted origins.

The point is that I need to "cherrypick" some mailing addresses out of this
domain and process them (for mailing list processing), while relaying most
on. If I have the

example.com anything

line, then it rejects userexample.com as "status=bounced (unknown user:
"userexample.com")" even with the entry in transports. If I don't have
it, it does the right thing with locally originated mail - it looks it up
in transports (which is what I want since I will be the terminal MX) and
sends it out. The problem is that I am having trouble setting up a test
case since I do not have a good domain that I can cripple mail delivery for.

There is a third party that is going to make my servers the destination for
their DNS, and I don't have any control on when this happens, so I have to
be ready.

Without the "anything" in the virtual map, do I need to add the domain to
relay_domains to make this work?
