Comment 2 for bug 266201

No I have not - this was the problem.

Please could you add a section to the docs that points this
out about setting up SSL - it's way too easy to overlook a
tiny option such as this one.

In theory there is no need for mailman to post to an
absolute URL that I am aware of - is it possible to change
it to access relative URLs? This will make mailman
significantly easier to use on SSL sites.
