EDIT: For better clarification, the www domain <rc-worms.de> is hosted on a different (dedicated) web server. Mailman is running on a vServer of its own, it just uses <rc-worms.de> as a nice readable domain for mail addresses, configured on the web server to forward each mail to the real physical (and not so nicely readable) address <any <any_mailing_l...@euve51864.serverprofi24.de>_ <any_mailing_l...@euve51864.serverprofi24.de>mailing <any_mailing_l...@euve51864.serverprofi24.de> _l...@euve51864.serverprofi24.de <any_mailing_l...@euve51864.serverprofi24.de>>.
