-G
Set gateway submission mode V8.10 and later
Use of the -G
command-line switch indicates to
sendmail that the message
being submitted from the command line is for
relaying, and is not an initial submission. This
switch is primarily intended for use by the
rmail(8) program, a part of
the UUCP suite of programs. Mail received by UUCP is
mail that did not originate at the local site. It is
intended to be relayed outward to other sites, or to
be delivered locally. Because mail received by UUCP
is not the initial (therefore, local) submission of
a message, sendmail needs to be
more strict about what it will accept.
A message received with the -G
switch specified will be rejected if
the address is not fully qualified. The -G
command-line switch
also tells sendmail to perform
no canonicalization on the address. Note that future
releases of sendmail might
reject improperly formed messages when this switch
is specified.
