Hi dear users, Recently we've added a new feature to our products that allows you to hide an anonymous subscription form for your public lists. The anonymous subscription form is available by default for every public list and looks like this: https://lists.mailman3.com/postorius/lists/announcements.mailman3.com/ It allows users without a Postorius account to seamlessly subscribe to the list. Unfortunately, it also attracts some spammy subscriptions. We are now able to completely remove this form from the Postorius UI hence making spammers' lives a bit harder. (However, they will be still capable of creating a subscription request by sending an email directly to the list-join@domain.tld address.) If you want this feature enabled for your server (it's server-wise, not list-specific), please send your request to support@mailman3.com. Sincerely, Mailman3.com
