The mailing list for listmasters using Sympa

[<address@concealed>]

Hi,
I'm wondering if I can configure a list so that a non-subscriber can post to
it using a web interface (with a captcha or some other mechanism to make sure
they are human).

I'd like people to be able to post questions to the list and read the answers
in the web archive (and possibly reply to them the same way) without having to
subscribe.

Does Sympa support that?

Thanks
Dan
