core-libs-dev email delivery

[Florian Weimer]

We used to have a problem where hotspot-dev mail did not get delivered
to list subscribers.  Is it possible that a similar issue now affects
core-libs-dev?  I don't receive mail on two separate mail accounts,
with completely different infrastructure on my end.  The last message
I received is:

From: Brian Goetz <brian.goetz at oracle.com>
Subject: Re: 8251989: Unified Hex formatting and parsing utility

I tried to resubscribe in case I got unsubscribed by accident, but I
did not receive a confirmation message or the usual Mailman privacy
alert for a second subscription attempt.
