Configuring advanced anti-spam options<br />

11-18 Electronic Mail<br />

The following is an example <strong>of</strong> a DROP action that will delete the<br />

message from the MTA without delivering it to the recipient or saving<br />

a copy <strong>of</strong> the message for later handling:<br />

threshold=**%;action=DROP<br />

About the REFUSE action<br />

This action rejects suspected spam at the gateway and allows the<br />

sender to receive a customized return message, simulating the<br />

absence <strong>of</strong> a mailbox. The following options can be specified for this<br />

action:<br />

rcode—This option specifies the main SMTP response code. This is<br />

specified in RFC 821.<br />

xcode—This option specifies the secondary SMTP response code.<br />

This is specified in RFC 2034.<br />

msg—This option specifies the text that will be contained in the<br />

error message that is returned to the sender. For example, Delivery<br />

denied. Mailbox unknown.<br />

The following is an example <strong>of</strong> a REFUSE action that will cause mail<br />

suspected <strong>of</strong> being spam to be discarded at the gateway. The message<br />

“Delivery Denied.” will be returned to the sender.<br />

threshold=**%;action=REFUSE;config=[rcode=500;<br />

xcode=5.0.0;text=[Delivery Denied.]]<br />

About the SAVE action<br />

Important: If your site handles a large amount <strong>of</strong> spam messages, the disk space<br />

required to store saved messages can become significant. You may need to delete the<br />

saved mailboxes periodically in this case.<br />

This action stores the message in a designated location without<br />

delivering a copy to the recipient. The message can then be<br />

examined, deleted, or forwarded to the intended recipient by an<br />

administrator. The following options can be specified for this action:<br />

path—The path for this value is preset as<br />

/var/spool/authority/saved. Do not modify the path value.<br />

depth—This option indicates the depth <strong>of</strong> the file within the<br />

directory. The default is 0.
