Prior to Wietse's earlier post on this thread, I didn't know you could
alias a non existent address back on itself in order to make the
address known to Postfix. That's simply clever! I did know you can't
silently discard messages using Transport if the address didn't exist,
nor by aliasing such an address to an existing mailbox if the
destination accepts mail. I don't reject 'noreply' addresses myself,
but would opt for Wietse's method should I ever feel the need to do
so. Both methods work though.

Obviously not, since Wietse posted:
transport_maps = inline:{u...@example.com=discard:}
Unfortunately, transport_maps does not decide what addresses are valid;
that decision is based on virtual_alias_maps, local_recipient_maps,
relay_recipient_maps, and virtual_mailbox_maps.
