I analyzed the incoming spam from the first one that appeared. 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?
