Hi,
I was create email account ds[at]didiksetiawan.com. Then, I subscribe on mailinglist vger.kernel.org. About a month ago, I can't receive message anymore from that mailinglist. I try to unsubscribe & subscribe again, but this is what I get as the response:

But when I try to send & receive mail from other domains such as gmail.com, yahoo.com, etc. I got normal responses.
Any ideas? Please tell me if I did anything wrong.
TIA.
