Spam Control

Unsolicited electronic mail is colloquially known as "spam." The restriction of mail based on originator is known as spam control. The SMTP proxy provides the ability to define a list of one or more restrictors that operate based on either server name (suffix) or nonserver (address range) criteria.

Spam restrictors have one of two syntactic forms:

• server suffix (suffix in a named host), or

• start address [..  end address] (range of one or more IP addresses of unnamed hosts)

  ---

  Note -

  No spaces are permitted around the double dots (..) in this construct for the address range.

  ---

server suffix is simply an ASCII character string.

See "SMTP Proxy Operation" for details regarding how these restrictors are used.

Spam restrictors are defined using the configuration editor, and the mail_spam subcommand of ssadm edit in the administration GUI.
