NAME
ezmlm-reject - reject messages unsuitable for
distribution
SYNOPSIS
ezmlm-reject [ -bBcChHqQsStT ][
dir ]
DESCRIPTION
ezmlm-reject reads a mail message from
its standard input. It rejects the message if it sees something it
doesn't like.
If the message has a ``Precedence: junk'' header,
ezmlm-reject exits 99 causing the message to be ignored.
This causes replies from (some) vacation programs to be ignored.
If dir is specified, ezmlm-reject reads
dir/msgsize for a maximum:minimum message body size
in bytes. Either number will be ignored if 0 or omitted.
ezmlm-reject will also look for dir/mimereject
and dir/mimeremove. if dir/mimereject
exists, Messages of the Content-Types specified or with MIME parts
of these types will be rejected. If dir/mimeremove
exists, ezmlm-reject will reject messages of the
Content-Types specified. These content-types will be accepted as
parts of a composite MIME message. They will be stripped out later
by ezmlm-send(1).
ezmlm-reject will exit 100 (permanent error) for
rejections. If the list address is not in the message ``To:'' or
``Cc:'' headers and the -t switch is active, the exit code
is 100 or 99, depending on the -q switch (see below). If you
would like to forward messages instead of rejecting them, you can
into the appropriate .qmail file put:
|condredirect
newaddress except /path/ezmlm-reject DIR
Now rejected posts will go to this address, and the recipient
can take appropriate action.
OPTIONS
- -b
- Reject the message if the message body starts ``subscribe'' or
``unsubscribe''. If the -c switch is specified, messages
will also be rejected if the subject starts with these words.
-B (Default.) Do not reject messages starting ``subscribe''
or ``unsubscribe''.
- -c
- (Default.) Commands are not permitted in the Subject line. A
Subject line consisting solely of HELP, REMOVE, SUBSCRIBE, or
UNSUBSCRIBE is rejected.
- -C
- Commands are permitted in the subject line.
- -h
- Reject message if any of the headers in
dir/headerreject occur in the header. Mailing-List
headers of other mailing list managers can be put into this file,
one per line, to prevent processing of messages from other mailing
lists. dir must be specified.
A reasonable set of headers would be: ``Mailing-List'',
``X-ml-name'',
``ml-name'',``X-loop'',``X-listprocessor-version'',``X-mailing-list''.
Case is not important.
- -H
- (Default.) Ignore dir/headerreject. -q
Quiet. If the message due to the lack of the list address (see
-t) is not accepted, this is logged but no error message is
sent to the sender.
- -q
- Quiet. If a message due to the lack of the list address (see
-t) is not accepted, the message is silently ignored.
- -Q
- (Default.) Not quiet. If a message due to the lack of the list
address (see -t) is not accepted, the sender is notified by
an error message.
- -s
- (Default.) A nonempty Subject line is required.
- -S
- A Subject line is not required.
- -t
- (Default.) Reject messages that do not have the list address in
the ``To:'' or ``Cc:'' header(s). ezmlm-reject needs access
to dir/outhost and dir/outlocal to
check this. This check is silently omitted if dir is not
specified, to assure backwards compatibility with existing ezmlm
lists.
- -T
- Do not require the list address in the ``To:'' or ``Cc:''
header(s).
BUGS
ezmlm-reject does not handle rfc822 comments in
``Content-Type:'' lines if present before the type or boundary.
This could be used to defeat the MIME rejection function. OTOH,
this function is intended to reduce garbage, not guarantee its
elimination.
