I have had that problem, too. Maintainers give contact details, but then
I have to jump through hoops before I can actually contact them. I see
why people want to protect themselves from spam, but this approach seems
counter-productive to me.

The way to accomplish that is to configure the list as "moderated", and
to set all list subscribers as "unmoderated". This makes postings from
subscribers go right through, and everyone else's message are forwarded
to the list moderator for approval. It's not quite the same as a
challenge-response scheme that empowers casual posters to confirm their
honest intentions (i.e. the correctness of their mail envelope address),
but it's still a lot better than just dropping every mail from anyone
who isn't subscribed.

Take care,
