All these cases had one thing in common: they were not sent by e-mail, but via the Hyperkitty web interface. This means that the spammer made an effort for him to join the conference, confirm the verification email for the subscription, log in to the web interface and take advantage of the fact that with Hyperkitty it is possible to use the mailing list in a way like a web forum. For this reason, the post was first processed by Mailman, who creates emails for individual participants. Only then, these emails were processed by the mail server, which has an integrated spam filter. Therefore, these emails had the advantage of spam ratings, as they were created locally. The question is how to deal with it? Each of these emails was sent from a different address - different participants => it will not be effective to block a specific participants here. And since spams sent in this way are currently very rare cases, it seems too restrictive to prevent the use of Hyperkitty for posting to mailing lists. I suggest waiting to see if sending spam in this way will continue to be negligible or increase. And decide according to how it will continue. I believe that the necessary input effort is so large that it is unlikely to bring the expected result for spammers. That's why I hope that spam doesn't have to increase. What is your opinion? Cheers
