Summary: check for subscriber fails w/ moderated

Initial Comment:
When you run a list that is non-moderated, but you limit 
posts to the subscribers list, a post by a non-member 
results in this error:

Reason: Post by non-member to a members-only list

If you go into "Privacy Options" and change "Must posts 
be approved by an administrator?" and 
maintain "Restrict posting privilege to list members" a 
post by a non-subscriber results in THIS reason:

Reason:  Post to moderated list

Unless I am missing a configuration option, I believe this 
is a flaw in the order in which mailman is checking 
posts.  Even if a list is moderated, the reason this 
individual post was rejected should still read

Reason: Post by non-member to a members-only list

or, a new reason should be made like this:

Reason: Post by a non-member to a members-only 
AND moderated list

This may seem like a silly request, but if you run a 
members only list that happens to be moderated as 
well, you run into the problem of accidentally approving a 
post from a non-member when the content of that post 
was "on topic".

Is there a fix for this?  Would this classify as a bug?

Does anyone know of any other work arounds?

When you have a few thousand people on a mailing list, 
its not really easy to realize on your own that a specific 
individual isn't a subscriber to the list.  Especially when 
you have multiple individuals help administrate the list 
itself.

I'm closing this bug report, because I've commented
favorably on the patch you posted, even though (sadly) it
won't be applied to MM2.0.x and isn't applicable to MM2.1.

I've been experimenting with Mailman/Handlers/Hold.py 
(playing with python for the first time ever) and after spending 
some time trying to figure out how to compile it, I came up 
with a simple idea.

I moved the code that checks if the list is moderated to 
immediately after the code that checks if the list 
is "subscriber only" and the post is coming from a subscriber 
or not.

The result:  Exactly what I want.   However, I don't know if I've 
managed to miss something obvious by doing this.  Have I 
possibly broken an aspect of Mailman and I'm not realizing it?

With this modification to Hold.py a post from a non-
subscriber to a moderated (and subscriber only) list ends up 
in the administrative queue with a reason of "Post by non-
member to member-only list" instead of a moderated list 
bounce.  This seems like the logical and proper way for this 
to operate.

Can someone tell me if this appears to be a safe and proper 
solution?   If so, I think it should be rolled into the current 
version.  I generated a patch file with diff -C 2, attached here, 
but possibly not created properly.  Beware when running it! :)
