''FEATURE(access_db)'' '''


A database for mail policy V8.9 and above

Prior to V8.9, the only way to accept or reject mail from selected sites was to use tcpwrappers, or to write your own custom rule sets and rules. Beginning with V8.9, sendmail offers a database which provides that same service, and more (such as feature selection and policy control), in a much more easily configurable way. See Section 7.5 for a detailed description of this feature.
