NAME
ezmlm-gate - Gate posts depending on message SENDER
SYNOPSIS
ezmlm-gate [-cCmMpPrRsSvV] [-q file] dir
[moddir1] [moddir2 ...]
DESCRIPTION
ezmlm-gate checks if SENDER is in it
least one of the subscriber 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.
The default is to send the message for moderation.
OPTIONS
- -cCmMpPrRsS
- Passed on to ezmlm-store(1)
and ezmlm-send(1).
- -cCrR
- Passed on to ezmlm-send(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 .
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
moddir1, moddir2, 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.
- -v
- Display version information.
- -V
- Display version information.
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'.
