Abstract

Specifies non-POSTMASTER users who are allowed to post to the ALL-REQUEST alias.


Example

z/VM:

ALL_REQUEST_ALLOWED_USERS = 'joe@example.com pete@abc.unix.example.org'

Unix:

ALL_REQUEST_ALLOWED_USERS=joe@example.com pete@abc.unix.example.org

export ALL_REQUEST_ALLOWED_USERS

Windows:

ALL_REQUEST_ALLOWED_USERS=joe@example.com pete@abc.unix.example.org


Details

The ability to post to the ALL-REQUEST alias, which expands to all non-quiet list owners, is restricted as follows: 

      1. The site configuration variable, ALL_REQUEST_ALLOWED_USERS, can be used to specify who can mail to ALL-REQUEST. This variable uses the same syntax as POSTMASTER=, in other words, a space-separated list of userid@host specifications.
      2. Postmasters are always allowed to mail to ALL-REQUEST, even when not listed in ALL_REQUEST_ALLOWED_USERS. 
      3. The determination is made conclusively on the RFC821 MAIL FROM because: 
        • This avoids dealing with header errors. Header error = don't know who sent this = discard silently = unhappy admin who had to send an urgent notice to all his owners. 
        • The main point of this change is to block spammers, and spammers typically have non-working or null MAIL FROM: addresses. Needless to say, null doesn't pass the test. 
      1. When the MAIL FROM is not null, the REQNAK1 mail template form is sent when the message is rejected.


Default Value
