HELP-PROMPT: Answer must be 3-30 characters in length.
DESCRIPTION: If you answered YES to PREVENT MESSAGE RELAYING? (field #40), to stop your site from relaying messages from outside sites through your site to other outside sites, you may add entries here, in order to define what is an
"inside" site, or sites whose messages your site is willing to relay.
For example, if your site is a VA site, then other VA sites are "inside" sites, and your site should relay mail for them. So, any site whose domain name ends in ".VA.GOV" is an "inside" site. So VA sites should have
only one record in this multiple, and it should be ".VA.GOV".
The default, if there are no entries in this multiple, is your site's domain name.
MailMan will check the site name of any site which connects to it, and identifies itself in the SMTP HELO command. If the sitename ends in any of the entries in this multiple, then any mail coming from that
site through your site to other sites, will be accepted and relayed onward.
If the sitename does not end in any of the entries in this multiple, then messages will only be accepted that are addressed to recipients whose sitenames end in one of the entries in this multiple. Otherwise, the site
will receive an error message telling it that relaying is denied, and messages will not be accepted for relaying onward.
