Well, I actually received what appears to be a SPAM response to my original email post. No joke. If mods want a copy of it, let me know.

Hi Everyone,
I’ve seen a recent uptick in SPAM messages making it into mailing lists. Looking at the raw, it seems that the e-mails are being submitted thru the Postorius/Hyperkitty “Start a New Thread” interface. Is there a way to turn that off? We would want people to only be able to post via e-mail. Part of the problem is that our anti-spam system RSPAMD trusts the mailman-web IP… so it doesn’t scan things originating from there.. ☹
Another uestion: Is there a way to implement captcha, or is there a recommended gate that can be put in the signup process? Apparently bots are finding a way thru the signup process, and then sending messages to the list via the Postorius web interface. There seems to be a Django plugin for it; but it appears the Mailman code would have to be adjusted to implement it.
I’m open to any suggestions, including on places to check for misconfiguration. 😊
Thanks.
