If that last sentence above is confusing, then I can invert the
text to make it consistent with its context.
(no change) Request that the Postfix SMTP server rejects mail
for unknown recipient addresses, even when no explicit
reject_unlisted_recipient access restriction is specified. This
prevents the Postfix queue from filling up with undeliverable
MAILER-DAEMON messages.
(inverted) The recipient address is unknown when it does not
match a virtual(5) alias or a canonical(5) table, plus one of
the following conditions holds:
> *The recipient domain matches $mydestination, $inet_interfaces or
> $proxy_interfaces, but the recipient is not listed in $local_recipient_maps,
> and $local_recipient_maps is not null.
> *The recipient domain matches $virtual_alias_domains but the recipient is not
> listed in $virtual_alias_maps.
> *The recipient domain matches $virtual_mailbox_domains but the recipient is
> not listed in $virtual_mailbox_maps, and $virtual_mailbox_maps is not null.
> *The recipient domain matches $relay_domains but the recipient is not listed
> in $relay_recipient_maps, and $relay_recipient_maps is not null.
