No. Not seeing these. Your message didn't arrive either. I found this
in the postfix logs:

2025-06-18T11:49:48+01:00 DiskStation1 postfix/smtpd[810]: NOQUEUE:
reject: RCPT from lists.ubuntu.com[185.125.189.65]: 554 5.7.1 Service
unavailable; Client host [185.125.189.65] blocked using
sbl.spamhaus.org; Error: open resolver;
https://check.spamhaus.org/returnc/pub/2400:cb00:913:1024::ac45:f705/;
from=<ubuntu-users-bounces at lists.ubuntu.com> to=<tony at acasystems.org>
proto=ESMTP helo=<lists.ubuntu.com>

So, I've turned off DNS-based Blackhole List filter. Could you try
replying to the list please? Hopefully, it'll get through this time!

Regards,
Tony.
