At first, I noticed dropped posts from mailing list subscriptions relative to the list web archives. I posted the suggested noticed to the Comcast RBL admins, so far to no avail other than a to yield a more complete stop. The mail forwarding has been disabled for now, and I am dealing with this more manually.
If you tried to contact me in the last few days and have not gotten a response, please resend your mail. I should now be in a position to receive it. Sorry for any inconveniences.
Offers of better mail hosting would be gladly accepted, of course.
