Has vger.kernel.org started blocking whole .info domain in recent days ?

I've been subscribed for many years to many lists - including occasional participation/bug reports/patches. But since a few days no mail has arrived and any attempt at (re)subscribing bounce with "553/5.7.1/policy analysis reported: Your address is not liked source for email". At the same time subscribing with alias under .com domain (via the same server) works fine.
