Yes, I know about it, I've had it set.

I'm viewing "http://www.postfix.org/OVERVIEW.html#delivering";. The
local(8) and virtual(8) are at the same level. Why local(8) return
SMTP-error and virtual(8) generate bounce mail?
I tried turn on debug (with debug_peer_level and debug_peer_list). I added
"reject_unverified_recipient" to "smtpd_recipient_restrictions". I see in
maillog that verify(8) tests deliverability using only lookup in
"/etc/postfix/vmailbox", no test execute locdel-transport. This is
logical, because executing a final delivery program causes a delivery
process.
So how to solve it? There is "address_verify_virtual_transport". May
be use external program for "address_verify_virtual_transport" returning
error if mail is not deliverable. Anyone have experience with this?
