Trouble with xfs mailing list subscription

[Michael Lueck]

Greetings,

I was previously subscribed to the xfs mailing list, in non-deliver mode as I use the gmane NNTP gateway to read messages.

Suddenly my ID is not allowed to post. I tried checking my subscription, and the following rejection is returned.

This message was created automatically by mail delivery software.

its recipients. This is a permanent error. The following address

Sender IP address rejected
