[Mailman-Users] some mailman interface links are http:// instead https://..

[Knut Krüger]

version 2.1.23 <http://www.gnu.org/software/mailman/index.html> Debian 
Stretch

There are some pages of the administration interface which are using 
http:// instead of https://

f.e the admin interface of the Held Messages are not working:
http://mydomain.com/cgi-bin/mailman/admindb/Mylist

[Posting Held for Approval]

using Defer, Approve, Reject, Discard and [Submit All Data] is causing 
Firefox to show an warning (using unencrypted connection)
and it is impossible to delete the held messages.

All links at the https://mydomain.com/cgi-bin/mailman/admindb/Mylist  
(Held Messages)page are linked without https://

The mails for the reminder that there are messages to administrate are 
sent without https:// the server changes to https:/ automatically

Regards Knut
