[MM3-users] Re: The MAILMAN_ARCHIVER_KEY was not sent as the Authorization HTTP header.

Finally have found my issue... Apache automatically removes the header, see https://stackoverflow.com/questions/26549250/apache-strips-down-authorizatio... . Hope it can be useful for somebody else!

Thank you for all the informations shared with me, Mark. Hope to hear from you soon! And kudos to you and the group of volunteers.
