Here's what rfc2142 has to say (see http://www.roxen.com/rfc/rfc2142.html )

>6. MAILING LIST ADMINISTRATION MAILBOX
>
>
>Mailing lists have an administrative mailbox name to which add/drop
>requests and other meta-queries can be sent.
>For a mailing list whose submission mailbox name is:
>      <LIST@DOMAIN>
>
>
>there MUST be the administrative mailbox name:
>      <LIST-REQUEST@DOMAIN>
>
>
>Distribution List management software, such as MajorDomo and Listserv,
>also have a single mailbox name associated with the software on that
>system -- usually the name of the software -- rather than a particular
>list on that system. Use of such mailbox names requires participants to
>know the type of list software employed at the site. This is
>problematic. Consequently:
>      LIST-SPECIFIC (-REQUEST) MAILBOX NAMES ARE REQUIRED,
>      INDEPENDENT OF THE AVAILABILITY OF GENERIC LIST SOFTWARE
>      MAILBOX NAMES.
