Yes ... and no - sort of mostly.
Did wee search of my email, I have one quite similar, but from months ago.

Looks to me likely some backscatter crud from some
drain bamaged mail misconfiguration or (dis)service,
from/via some subscriber on the SF-LUG list.

Bit more research and ...
yeah, at least from the one I received, doesn't appear to have enough detail,
even with full headers, to identify the problematic list subscriber.  :-/

Dug into logs on linuxmafia.com ... found corresponding email addresses ...
checked (my automagic backup copies of) SF-LUG subscriber list,
found pair of matching email addresses, of form:
#@sms.message-service.org
#@tts.message-service.org
Where both of those have for # the same 10-digit number,
which would appear to be a phone number.

I sent text message to that phone number,
effectively telling them they ought not subscribe such an email address
(and I gave the two subscribed) that cause such backscatter.

If they don't fix it, mail admin could, e.g.
unsubscribe the address(es),
ban the address(es) (or even domain(s)) from subscribing.

Oh, also looking over my version control (RCS) on changes of subscribers,
looks like they added those two addresses around
2026-07-19T13:27:28Z, or up to about 24 hours earlier than that
(the sync, comparison, and change tracking generally occurs daily)

The earlier backscatter I got was 2026-09-01
(apparently/presumably triggered from my monthly posting
of the list stats).

Anyway, maybe at least from my text that I sent to the number,
they'll self-correct and unsubscribe the offending email address(es).
