Since you have 'reject_unverified_recipient', Postfix will check with
the LMTP server whether or not the recipient exists.

Did you read the text you quoted above? I specifically said you do *not*
want to use /etc/postfix/virtual for this.

What do you have in hash:/etc/postfix/maps/mailbox? If this is a
complete list of all addresses at your virtual_mailbox_domains, you can
remove reject_unverified_recipient; otherwise, you want to remove
virtual_mailbox_maps.
