NNNNAAAAMMMMEEEE
     ezmlm-limit - Limits traffic to list

SSSSYYYYNNNNOOOOPPPPSSSSIIIISSSS
     eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt [ ----ffff _f_i_l_e ][ ----ddddDDDDFFFF ][ -tttt _s_e_c_s ][ ----nnnn _m_s_g_s ] _d_i_r

     eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt is intended to limit traffic to a list  in  case
     an  outside source sends excessive messages. Traffic is lim-
     ited by converting the list to a message moderated list,  or
     by deferring messages.

     eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt reads _d_i_r////llllooooooooppppnnnnuuuummmm.  If it does not exist or con-
     tains  a  time  stamp  more  than  _s_e_c_s  seconds  old, it is
     updated.  If it exists, contains a time stamp less than _s_e_c_s
     seconds  old,  and  _m_s_g_s  messages or more have passed since
     _d_i_r////llllooooooooppppnnnnuuuummmm was created,  eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt  creates  _d_i_r////mmmmooooddddppppoooosssstttt.
     For  lists set up with eeeezzzzmmmmllllmmmm----ssssttttoooorrrreeee((((1111)))) this results in future
     messages being moderated.

     As long as _d_i_r////mmmmooooddddppppoooosssstttt does not exist,  eeeezzzzmmmmllllmmmm----ssssttttoooorrrreeee((((1111))))  will
     simply   forward   the   message   to  eeeezzzzmmmmllllmmmm----sssseeeennnndddd((((1111))))....   Once
     _d_i_r////mmmmooooddddppppoooosssstttt exists, messages will be queued for  moderation.
     Thus,   in   case  of  error  (such  as  misconfigured  auto
     responders) subscribers are spared messages in excess of the
     limit. However, no messages are lost, since the moderator(s)
     can (selectively) approve queued messages.

     If _d_i_r////mmmmooooddddppppoooosssstttt already exists, eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt will not take any
     action.

     Resetting   the   list   requires    manual    removal    of
     _d_i_r////mmmmooooddddppppoooosssstttt._Q_u_e_u_e_dmessages_c_a_nbe  or  approved  in  bulk with
     eeeezzzzmmmmllllmmmm----aaaacccccccceeeepppptttt((((1111)))).

     eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt is not required for normal  lists,  since  qmail
     and  ezmlm loop detection prevent problems caused by regular
     bounces. However, it affords some protection against malice,
     and severely misconfigured subscribers.


OOOOPPPPTTTTIIIIOOOONNNNSSSS
     -dddd   Defer excess traffic. Excess messages are deferred  and
          qmail  will  re-deliver. As a consequence, traffic will
          be throttled to  the  maximum  allowed.  Due  to  qmail
          delivery  back-off, messages may not be disseminated in
          the order received. If traffic is continuously above or
          close  to the limit, some messages may be delayed for a
          long time or even bounced.

     -DDDD   (Default.)  Make the list moderated once excess traffic
          is detected. This requires the list to be configured up
          with eeeezzzzmmmmllllmmmm----ssssttttoooorrrreeee((((1111)))) rather than eeeezzzzmmmmllllmmmm----sssseeeennnndddd((((1111)))), which is

          easiest  done  by  first  creating  a message moderated
          list, then removing _d_i_r////mmmmooooddddppppoooosssstttt.

     -nnnn _m_s_g_s
          Trigger after _m_s_g_s messages (default 30).

     -ffff _f_i_l_e
          Instead of _d_i_r////llllooooooooppppnnnnuuuummmm use _f_i_l_e as the time stamp. This
          allows the use of multiple instances of eeeezzzzmmmmllllmmmm----lllliiiimmmmiiiitttt for
          the same list. For instance, you may allow 60  messages
          per  hour  with  one  instance and 150 messages per day
          with another. If _f_i_l_e is relative, this is relative  to
          _d_i_r.

     -FFFF   (Default.)  Use _d_i_r////llllooooooooppppnnnnuuuummmm as the time stamp.

     -tttt _s_e_c_s
          Check the number of  messages  within  period  of  _s_e_c_s
          seconds (default 3600 seconds).
