A message that you sent could not be delivered to one or more of its recipients. This is a permanent The following address failed:

owner@lists.cpunks.org: SMTP error from remote server for RCPT TO command, host: mail.pglaf.org (65.50.255.19) reason: 550 5.1.1 : Recipient address rejected:

Why? No owner ?

cypherpunks-owner@lists.cpunks.org is me. There's no "owner@" address. That's not the standard that Mailman uses, since any given site might have many lists.

From what you forwarded, it seems someone attempted shenanigans, but didn't succeed. There's not much that can be done about this, since it seems the Mailman software is performing as intended.
