Ummmmm, you don't use SMTP at all to construct these maps... So no
VERIFY strangeness or somesuch come into play.
Either construct the map file(s) by hand or use some scripted method
(some are mentioned in the wiki, as you might know)... The maps would
look something like
user1 at domain1.tld OK
user2 at domain1.tld OK
etc.
You need postmap the files so that they become hashed db files, else
nothing will work.
I'd suggest you create one map per domain, and construct one script
per domain to update them periodically (on a busy system every 15
minutes could be about right).
Of course you need make sure the files contain every possible
permutation ... aliases and all. But you should be able to test things
out before actually committing it to postfix.
