NAME
       ezmlm-gate - Gate posts depending on message SENDER

SYNOPSIS
       ezmlm-gate [-cCmMpPrRsSvV] dir [moddir1] [moddir2 ...]

DESCRIPTION
       ezmlm-gate checks if SENDER is in it least one of the sub-
       scriber lists with base directory moddir1,  moddir2,  etc.
       If it is, the message is posted via ezmlm-send to the list
       in dir.  If not, the message is sent  for  moderation  via
       ezmlm-store.

       If moddir1 is not specified, dir is used.

              Other options are passed on if appropriate for exe-
              cution of ezmlm-store or  ezmlm-send.   ezmlm-store
              and ezmlm-send have non-overlapping options.

USAGE
       ezmlm-gate 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  ezmlm-store(1).

       Set  up  the list with a ezmlm-gate line in dir/editor and
       touch dir/modpost.  Add the moderator(s) (usually the list
       owner):

       ezmlm-sub dir/mod moderator@host

       This  will  via  ezmlm-send  directly distribute all posts
       from subscriber addresses and send out the rest for moder-
       ation  to  the moderator(s) via ezmlm-store.  To test sev-
       eral subscriber databases, e.g. the  list  and  the  list-
       digest subscribers, add the corresponding list directories
       to the ezmlm-gate 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'  sub-
       directory  of it, and add 'addl' to the ezmlm-gate command
       line. Now just add all problem  addresses  to  the  'addl'
       address  database  using  ezmlm-sub.   The entire point is

                                                                1

ezmlm-gate(1)                                       ezmlm-gate(1)

       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, legit-
       imate users are never rejected and 'aliases' rapidly iden-
       tified by the owner/moderator and their handling automated
       one by one, by simply adding them to 'addl'.
