Another way to deal with this is sender confirmation by email, where, like subscriber confirmation by email, a message is sent with a confirmation link. Mailman doesn't have this capability presently but it seems to me that since it already has subscriber confirmation, it should be possible to adapt that sender confirmation.
This sender confirmation by email feature is available in L-Soft's LISTSERV, and it is an essential way to avoid fake email.
In a post a few years ago Barry said that this feature was going to be in vers. 2.2, but that version never materialized. Will it be in vers. 3?
Sort of. What I was talking about was using mail-back confirmation as an option for allowing postings from email addresses that Mailman has never seen before (i.e. non-validated). The confirmation message would be a sort of on-demand validation that would optionally be enough to allow that email address to post to the list. It still doesn't solve any of the authentication problems with those email addresses.
