I want to delete the mailman mailing list for leksah (leksah@projects.haskell.org.), since it is not used anymore and only collects spam. It looks as I can't do this on my own, so I need help. My mails to support@community.haskell.org didn't produce any response. 

So I try this for years now. Please! Is someone out there that can help me?

Kind regards
Jürgen Nicklisch-Franken
