That sounds like it would work.
In recap for Announce only lists:
1. List-Post: NO in the headers of the email.
2. Automatic Bounce of posts except from those already set in the Poster
option with a message stating "This is an announce only list."
3. A way to use a different "$home_prefix/templates/subscribeack.txt" so
that the "NO POSTING" could be clearly indicated when the user signed up.
This would help with the consistency problems I noted earlier. (The listinfo
page can already be changed manually without any problems.)
The only problem I can see with this would be this:
Having implicitly allowed certain email addresses to post to the list
*without* approval could be problematic if someone decides to send an email
as that user.
Simply looking over the posted items on the lists would give you the email
addresses that you could set up in your mail reader and you may be able to
post as that user unrestricted and unhindered.
What *may* be better could be a new parameter like "Authorized Submitters"
which would hold all the email addresses that were allowed to submit items
to the list. Those items that they sent would still have to be authorized by
a list admin BUT this could help with:
1. Spoofed email from those addresses.
2. Posting requests from people not on the list would be automatically
rejected if they're not on the list of "Authorized Submitters".
Make sense? Am I being too paranoid?
