       eezzmmllmm--ggaattee  checks if SENDER is in it least one of the subscriber lists
       with base directory _m_o_d_d_i_r_1, _m_o_d_d_i_r_2, etc.  If it is,  the  message  is
       posted  via eezzmmllmm--sseenndd to the list in _d_i_r.  If not, the message is sent
       for moderation via eezzmmllmm--ssttoorree.

       The default is to send the message for moderation.

       --qq _f_i_l_e
              Execute arbitration programs in _f_i_l_e.  Lines in  _f_i_l_e  are  exe-
              cuted just like in regular _._q_m_a_i_l files with the difference that
              all lines are assumed to be  program  names.  See  ddoott--qqmmaaiill((55)).
              Programs  are executed by /bin/sh and the message is on stdin of
              the executed program.  The leading ‘‘|’’ is  optional.  Comments
              and blank lines are allowed. If a program exits 111, delivery is
              deferred. If it exits 99, the message is sent to the list. If it
              exits  0,  the next line is executed. If it exits with any other
              exit code, the message is sent for moderation. Subscriber status
              per  _m_o_d_d_i_r_1,  _m_o_d_d_i_r_2,  etc, is tested only if all the programs
              have been executed and the final exit code is 0. Thus,  programs
              can  cause moderation (100), posting (99), or defer the decision
              to the next program and ultimately to subscriber status.

UUSSAAGGEE
       eezzmmllmm--ggaattee is best used if you want to  restrict  posts  to  a  set  of
       addresses  using  SENDER  checks. Obviously, this is not secure, but it
       can help quite a bit to keep garbage off  the  list.  For  more  secure
       setups, see eezzmmllmm--ssttoorree((11)).  For other arbitration such as SPAM protec-
       tion, use the --qq option. For instance,  invoking  eezzmmllmm--rreejjeecctt((11))  here
       would  cause  failing  messages  to  be sent for moderation rather that
       being rejected.

       Set up the list with a eezzmmllmm--ggaattee line in _d_i_r//eeddiittoorr and touch _d_i_r//mmoodd--
       ppoosstt.  Add the moderator(s) (usually the list owner):

       eezzmmllmm--ssuubb _d_i_r//mmoodd moderator@host

       This  will via eezzmmllmm--sseenndd directly distribute all posts from subscriber
       addresses and send out the rest for moderation to the moderator(s)  via
       eezzmmllmm--ssttoorree.   To  test several subscriber databases, e.g. the list and
       the list-digest subscribers, add the corresponding list directories  to
       the eezzmmllmm--ggaattee command line.

       This  can  be  expanded to include users that post from addresses other
       than the one they are subscribed  as:  just  create  another  directory
       ’addl’,  and  a ’subscribers’ subdirectory of it, and add ’addl’ to the
       eezzmmllmm--ggaattee command line. Now just add  all  problem  addresses  to  the
       ’addl’ address database using eezzmmllmm--ssuubb.  The entire point is that post
       from subscribers of any union of list go through, posts from identified
       ’aliases’  go through and all others go for approval to the list owner.
       Thus, legitimate users are never rejected and ’aliases’ rapidly identi-
       fied by the owner/moderator and their handling automated one by one, by
       simply adding them to ’addl’.
