How to unsubscribe from l10n SVN commit messages?

I still receive SVN commit messages for various sub-paths of to my email address

I already contacted admins of mailing list, but it seems I’m not subscribed to the list.

I suspect that there is somewhere a script also forwarding me those emails as I have been a KDE translator many years (read 10+) ago.

How can I unsubscribe from those messages?
