NAME
ezmlm-gate - Gate posts depending on message SENDER
SYNOPSIS
ezmlm-gate [-0cCmMpPrRsSvVyY] [-q file]
dir [modsubdir1] [modsubdir2 ...]
DESCRIPTION
ezmlm-gate
checks if SENDER is in it least one of the subscriber lists
with base directory
dir/modsubdir1,
dir/modsubdir2,
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.
The named subscriber list directories must be either relative to
dir
or fall within
dir.
The default is to send the message for moderation.
OPTIONS
- -cCQrR
-
Passed on to ezmlm-send(1) and ezmlm-store(1).
- -mMpPsSyY
-
Passed on to ezmlm-store(1).
- -q file
-
Execute arbitration programs in
file.
Lines in
file
are executed just like in regular
.qmail
files with the difference that all lines are assumed to be program
names. See
dot-qmail(5).
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
modsubdir1,
modsubdir2,
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.

(to stdout)
the command and arguments that would have been run.

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).
For other arbitration such as SPAM protection, use the
-q
option. For instance, invoking
ezmlm-reject(1)
here would cause failing messages to be sent for moderation rather that being
rejected.
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 moderation
to the moderator(s) via
ezmlm-store.
To test several 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' subdirectory 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 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 identified by the owner/moderator and
their handling automated one by one, by simply adding them to 'addl'.
