[-- Attachment #1.1: Type: text/plain, Size: 2350 bytes --]

Here are some patches mostly related to moderating emails for
discussion. I currently admin some lists with mailman, but would like
to move to mlmmj.

mlmmj-X-List-Administrivia_header.patch

	This patch adds two headers, an "X-List_administrivia: Yes" header
	for a few of the administrative messages that mlmmj sends out, and
	a header "X-mlmmj-mod-msg-id:" with the random string that is used
	as the argument for the 'moderate' command. The former is used
	similarly by mailman, and I filter based on it; I don't strictly
	need it if I have the latter header. The latter is really useful
	for writing scripts to moderate multiple messages at a time,
	rather than requiring them to parse out the Reply-To: header.

	If it's deemed worthwhile to keep the administrivia header,
	there's likely more locations that could use it, or it should
	just be added automatically in prepstdreply(). Another
	alternative would be to add these headers in the listtexts.

mlmmj-multiple_moderation_args.patch

	This patch adds the ability to moderate multiple messages by
	sending mlmmj a single message with multiple cookies addressed
	in the form

	  	listname+moderate-COOKIE[-COOKIE...]@domain.tld

	(This is one of my gripes with mailman, that in order to reject
	multiple spam messages by email, my script has to send a message
	for each message to reject, rather than just one message per
	list.) I left the moderation of subscriptions alone.

mlmmj-reject_command.patch

	This adds a 'reject' command to support rejecting messages for
	moderation, rather than accepting them as the 'moderate' command
	does. It supports rejecting multiple messages by taking messages
	in the form

		listname+reject-COOKIE[-COOKIE...]@domain.tld

	I didn't add support for rejecting subscriptions; that should
	probably be fixed.

mlmmj-add_moderator_command.patch

	This patch converts the From: address (currently
	"listname-moderators") in moderation messages to be a real address
	supported by mlmmj and adds the corresponding 'moderators'
	command. I'm not sure proper envelope filtering is done here,
	though.

As these patches touch similar areas of code, they are expected to be
applied in the order above.

Thanks.

(Note: some mail clients like mutt have hard coded limits on the length
of a To: address; e.g. mutt has a limit of 256 characters which it will
truncate if the address is longer than that.)
