Sort of. There's actually no concrete notion of an "announce-only"
list; IOW, there's no switch to pull to say this is or isn't an
announce-only list. In MM2.1, the way to do that is to
- turn on the moderation flag for all members
- set the default moderation action to discard (or hold if you don't
want to be so strict/nasty).
- turn off the moderation flag for the members who are allowed to post
- add any non-members who are allowed to post to the "accept these
That having been said, MM2.1beta2 will have the following controls on
the List-* headers:
- if the site administrator allows it, you can suppress all the List-*
headers for all messages. For MM2.1beta2, I'm going to change the
default to allow list owners to override the headers (the default
used to be to not allow overrides).
- there will be a separate config option to include the List-Post:
header. Set this to No if you're running an announce-only list
- List-Archive: will only be added if your list actually has archives
- List-Id: will always be added for all messages (unless suppression
of all rfc2369 headers is enabled).
- for non-administrivia messages (i.e. postings), List-Help:,
List-Unsubscribe:, and List-Subscribe: will be added (unless
suppression of all rfc2369 headers is enabled).
- for administrivia messages, those three headers will not be
included, but an X-List-Administrivia: header will be added instead
(again, unless all are suppressed).
I think that about covers all the bases, and should make everyone
