I was a user of the Geany Text editor years ago and during that time I signed up to the user list. For about a year now I have never used the editor and have since tried to unsubscribe from the list. I have tried to do this via the unsubscribe link from the mailing list's page and also by sending an email with unsubscribe as the subject to users-leave@lists.geany.org. However I still receive mails from the list and its been clutering my inbox. My only solution at the moment is to flag mails from geany as spam. But I don't want to do that since what I'm actually blocking are individual email addresses and besides its inefficient anyway. What other options do I have?
