ezmlm-reject - reject messages unsuitable for distribution


ezmlm-reject [ -cChHqQsStT ][ dir ]


ezmlm-reject reads a mail message from its standard input. It rejects the message if it sees something it doesn't like. 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 spec- ified or with MIME parts of these types will be rejected. If dir/mimeremove exists, ezmlm-reject will reject mes- sages 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 rejec- tions. 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 add ``|| exit 100'' to the ezmlm-reject line. Before that line, add an address, pointing to another .qmail file, e.g. ``list-rej@host''. Into that file, put (all on one line): |{ /path/ezmlm-reject DIR && exit 99 ; } ; exit 0 Followed by the address of e.g. the list owner. Now rejected posts will go to this address, and the list owner can take appropriate action.


-c (Default.) Commands are not permitted in the Sub- ject 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/header- reject 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 mes- sages from other mailing lists. dir must be speci- fied. A reasonable set of headers would be: ``Mailing- 1 ezmlm-reject(1) ezmlm-reject(1) 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 back- wards compatibility with existing ezmlm lists. -T Do not require the list address in the ``To:'' or ``Cc:'' header(s).


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.
