> Ian, I think that alternative is going to be Mailman 3 :). So, when is this going to be fixed in Mailman 3?
We have the end of 2022, and this bug from 2008 is still unfixed. I was able to generate backscatter to arbitrary addresses (Envelope-FROM) by sending (Envelope-RCPT) to an eMail address whose localpart is a nōn-existent list and whose domain is a server running Mailman 3 (stock from Debian). Thanks to this, the list server was just blacklisted by its provider, which is a very unfortunate situation. So, what can be done about this? Why can Mailman not just generate a list of valid addresses, which Postfix can then use? Ideally even via PostgreSQL to avoid the need for reloads (AIUI).
