mail_relay(4)

NAME
mail_relay - mail relay object for SunScreen SMTP proxy configuration

DESCRIPTION
A mail_relay object is one of the data objects that define a SunScreen configuration. It is manipulated through the configuration editor.

OBJECT STRUCTURE
mail_relay objects are unnamed. Each mail_relay object is identified by its ASCII-string value part. The value of any mail_relay is a Domain Naming System (DNS) domain suffix. This suffix is used, in conjunction with flags in SunScreen policy rules, to control the domain names to be allowed within recipients of SMTP-based mail messages processed by the SMTP proxy. Alternatively, the syntax of the value part of a mail_relay object provides for a negation effect; this is obtained by prefixing the value with an exclamation '!' character. This form of mail_relay value provides for passage denial of mail recipients. It can be used in conjunction with allowance values to provide control over access to sub-domains.
