RFC 822 6.3. Reserved Address It often is necessary to send mail to a site, without know- ing any of its valid addresses. For example, there may be mail system dysfunctions, or a user may wish to find out a person's correct address, at that site. This standard specifies a single, reserved mailbox address (local-part) which is to be valid at each site. Mail sent to that address is to be routed to a person responsible for the site's mail system or to a person with responsibility for general site operation. The name of the reserved local-part address is: Postmaster so that "Postmaster@domain" is required to be valid. Note: This reserved local-part must be matched without sensi- tivity to alphabetic case, so that "POSTMASTER", "postmas- ter", and even "poStmASteR" is to be accepted.

This occurs from typos, deleted users, and most of all spam programs trying random user names. I have just taken over the postmasters job and my mailbox is full of garbage that requires no follow up every hour. Freebsd 4.1-RELEASE with sendmail version 8.9.3.1 - Ernie.
