About the REFUSE action<br />

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

receive a customized return message, simulating the absence <strong>of</strong> a mailbox.<br />

The following options can be specified for this 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. This is<br />

specified in RFC 2034.<br />

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

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

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<br />

the saved mailboxes periodically in this case.<br />

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

copy to the recipient. The message can then be examined, deleted, or<br />

forwarded to the intended recipient by an administrator. The following options<br />

can be specified for this action:<br />

• path—The path for this value is preset as /var/spool/authority/saved. Do not<br />

modify the path value.<br />

• depth—This option indicates the depth <strong>of</strong> the file within the directory. The<br />

default is 0.<br />

• default domain—This option allows you to specify the domain that will be<br />

used if a recipient does not have a domain specified. The default is local.<br />

• method—This option specifies whether or not a unique mailbox will be<br />

created for each user in the designated directory, as follows:<br />

– individual: Specify this method to create a unique mailbox for each<br />

recipient.<br />

– consolidated: Specify this option to create a single, central mailbox.<br />

• cycle—If a consolidated mailbox is used, this option can be used to create<br />

additional consolidated mailboxes. You can specify that a new mailbox be<br />

created each hour (hourly) or each day (daily).
