Well, I tried using the Approved line method. But there were several
First, my mail client is pegasus 4.12a ono Win xp pro sp2. Mailman
Problem 1 is major. On my mailing list for the time being I have
several of my own email addresses. They are setup as separate
users (not separate identities) in pegasus. In some, but not all, I see
the approved line with password, ie it was not removed from the
Problem 2 is less grave but still a problem. The message now
arrives with a text attachment which is the footer for the mailing list.
So you no longer see it as part of the message, but as a separate
attachment. And since it contains info such as how to change list
options, I'd rather have it there in plain sight.
At this point I will go back to hiding the sender.
Thanks and comments appreciated.

It is fairly safe, but it could be safer. The issue here is that
anyone can post by spoofing the address of one of the unmoderated
posters. Since you have the list set to anonymous, these addresses
won't be totally obvious, but they still might be available for
example in the "list run by" link at the bottom of the listinfo page.
Also, with various malware harvesting addresses from people's
books it is even possible that some malware might mail itself to the
list while spoofing an authorized poster.

This is the safer way to do it. Everyone is moderated and any
post will be rejected no matter who it is from. Authorized posters
need to know the list password and put the line
either as a header if their MUA allows this conveniently or as the
first body line of the post. This allows the post to go directly to
the list. Note that if you put the Approved: line in the body, follow
it with a blank line as at least some Mailman versions remove the
following line when removing the Approved: line.
