anyone when routing is to the host, domain, or IP addresses listed. Note that RELAY
also includes the behavior of OK.
7.5.2.3 REJECT
The REJECT access database righthand value tells sendmail to reject the user, host,
domain, or address listed on the lefthand side. The rejection will use the default message
defined by the confREJECT_MSG mc macro (?§7.5.4 on page 283).
7.5.2.4 DISCARD
The DISCARD access database righthand value tells sendmail to accept any sender that
is listed on the lefthand side (either as a user, host, or IP address), but to silently discard
the message using the discard delivery agent (?§20.4.3 on page 719). The DISCARD
keyword can also be used for recipients if the FEATURE(blacklist_recipients)
(?§7.5.5 on page 284) is declared. When a recipient is discarded and when there are
other recipients in the envelope, all recipients are discarded. The one exception is if
DISCARD is returned to the check_compat rule set, established by the FEATURE(compat_
check) (?§7.5.7 on page 288), only the one recipient is discarded.
