The mailing list for listmasters using Sympa

[Ralf Ebeling <address@concealed>]

Hi,

I've a list configured as a newsletter -> only editors (moderators)
are allowed to post to the list...

I think it's easy to fake a mail coming from one of the editors;
therefore the mail is send to all subscribers.

Moderation isn't applicable because the only editor is a robot (a
PHP-Script) running at a foreign site.

I read something about md5, but I don't know how to use it...

Any hints?

Ralf
