Pre-emptive approval for non-members to post
The flip-side to this (which has already been implemented):
Non-members can post to our group. We want it that way so that various officials can distribute news etc. but not be privy to our discussions.
Unfortunately, we are now getting a lot of malware from unknown sources taking advantage of this open posting facility, even though the group is unlisted.
To combat this, I've turned on moderation for new members. That should mean any posts from new non-member addresses also have to be moderated (unless I've misunderstood and it doesn't work like that.)
Because certain people with known addresses post infrequently, what I want to be able to do is pre-approve them, in the same way that I can already pre-ban troublesome addresses.
At the moment, every time we get a malware post from a non-member, I have to ban that address. But the problem is, that only solves the problem if that address is used to send more malware. More often than not, of course, different addresses are used.
If all non-member posts went into a moderation pool, apart from posts from addresses either previously-approved or pre-approved,, that would solve the problem with minimum extra work and minimal chance of delay, since it is a small number of non-members that we want to allow to post.
A step better would be to be able to pre-approve non-member posting from particular domains. That would be even less work. I'd only have to enter a couple of domains. Problem solved.
Yes, I see what you mean, but then non-members would be able to convert themselves to members by attaching a YahooID to their mailing list entry...
I must say, the moderation for new members system has been working like a charm for combating the sudden plague of spam, but a pre-approval facility for specific non-member addresses to post would be the icing on the cake in terms of moderator workload.
What you are asking for is very fancy.
I think all you can do is send an invite - with the "add to mailing list"-box ticked !! - to the adresses you want to pre-approve, and set their subscription to "no mail"
