[LAU] Re: Signing up disabled for all mailing lists

Dear all, Unfortunately I had to disable signing up for all linuxaudio.org mailing lists. This is due to a flood of fake accounts being created that send out subscription confirmations which sometimes get flagged as spam. This in turn leads to so-called Feedback Loop complaints from the abuse team of our hosting service (Hetzner). If we get too much of those we risk getting our mail traffic blocked or ending up on a RBL (Realtime Blacklist). So at the moment new subscriptions can only be done manually through me. This is very inconvenient of course so if anyone knows a better way to shield Mailman3 against bots creating fake accounts then please contact me, thanks in advance! Best regards and happy holidays!!! Jeremy linuxaudio.org admin
