), represent a string.
The first character specifies the nature of the setting.
The value for the setting is placed between that character
and the asterisk. The value may be any string not
containing an asterisk, null, or newline. The values for
settings x and g are comma-separated lists of
strings. These strings may not contain asterisks, nulls,
newlines, or commas.
Specific comments on each option:
The determination of whether a message correctly identifies its sender is based on the most authoritative From or Sender field. For the purpose of this test, a plain Sender is taken to be more authoritative than a plain From. If a Resent-, Remailed-, or Redistributed- version of either a From or Sender field is given, it is taken to be more authoritative than the plain version of either. All such "Re" headers are taken to be equally authoritative, and the last one seen in the header (the one furthest down in the header) is taken to be most authoritative. To determine whether a message correctly identifies its sender, the local-address part of the most authoritative sender is looked up in the password file to map it to a uid, and that uid is compared to the invoking user's uid. If the uids match and the hostname part of the address is a name for the local system, the message correctly identifies its sender.
The S setting tells MMDF to use a Sender: field instead of a Source-Info: field, and also causes conflicting Sender: fields in the submitted header to be elided. This allows submission programs to send mail with a 'From:' field that does not match the identity of the invoking user without having to be privileged and without having a Source-Info: field added.

{ RFC 822 address }
In addition to those in RFC 822, the following address
delimiters are recognized within the local part of addresses
(in order of precedence):
@ % ! .
The ``!'' delimiter is interpreted as ``host!user'' while the others are interpreted as ``user?host''. For example, the address ``a.b!user%c@localhost'' would be queued for ``a.b!user@c''. The address ``a.b!user@localhost'' would be queued for ``user@a.b''. The address ``user.a@localhost'' would be queued for ``user@a''. Note that recognition of the ``.'' delimiter is a site-selectable option.
Also, addresses may be indirectly referenced, through a file
specification of the form:
``<filename'' or ``:include:filename''
where the angle-bracket must be the first non-blank character of the specification (to distinguish it from the ``<...>'' usage, above).
Addresses in the file may be separated by commas or newlines.
'', indicate that the
message is to be sent to recipients' mailboxes,
local mail should be sent immediately, return
mail goes to the submitter, and addresses are to
be extracted from the To: and cc:
components.
,'' with ``mlv'' as above and the
other settings indicating that mail for non-local
channels is to be sent immediately, the
author information is to be trusted, and the
``Received:'' component should cite the mail as being
relayed via Internet host VGR.BRL.MIL.
