Value Description
OK Accepts mail even if other rulesets rejects it. For
example, if the domain name is unresolvable.
RELAY Accepts mail addressed to the specified domain or
received from the specified domain for relaying
through your SMTP server. RELAY also serves as
an implicit OK for the other checks.
REJECT Rejects the sender or recipient with a
general-purpose message.
DISCARD Discards the message completely using the
$#discard mailer delivery agent. This only works
for sender addresses. That is, it indicates that
you must discard anything received from the
specified domain.
