OK - Accept mail even if other rules in the running ruleset would reject it, for example, if the domain name is unresolvable.
RELAY - Accept mail addressed to the indicated domain or received from the indicated domain for relaying through your SMTP server. RELAY also serves as an implicit OK for the other checks.
REJECT - Reject the sender/recipient with a general purpose message.
DISCARD - Discard the message completely using the $#discard mailer. For sender addresses it indicates that you should discard anything received from the indicated domain. If it is used for recipients, it affects only the designated recipients, not the whole message.
