Hi,

From Oct 11, I did not receive any emails from both linux-kernel and
netdev mailing list. Did anyone encounter the same issue? I subscribed
again and I can receive incoming emails now. However, I figured out
that anyone can unsubscribe your email without authentication. Maybe
it is just a one-time issue that someone accidentally unsubscribed my
email. But I would recommend that our admin can add one more
authentication step before unsubscription to make the process more
secure.

Thanks,
Lijun
