A couple of things I'd note about this.

First is that it's sent to [log in to unmask]  That's not
typically an address I'd expect to see associated with a mailing list
mailing so I wouldn't necessarily assume that it's generated by a
mailing list mailing.  (Other evidence may point to it being so, of
course.)  For instance if someone is issuing SUBSCRIBE requests using
an invalid email address you might see bounces like this.

I'd search the LISTSERV log file for robb@sanctum and similar to see
if LISTSERV's been receiving any mail from that address.

Just a thought,
