Yes, I am. I generating one hash lookup table of all mailboxes that require
a copy to be made.
After resolving all my aliases to a mailbox, I add_recipient for
'mailbox'@copydomain.com if I find it in my hash table.
Naturally, I only apply this to domains I am accepting email for and I don't
allow mailbox LHS clashes across my different domains.
It gets a little more complex without that restriction.
