That was my question as well, AFAIK that conforms to the requirements of a
List-ID header.
Looks legit to me.
This is the spec.

And here are the RFC 2919 examples for valid List-ID headers:

And dot-atom-text includes every character in the above:

Starts with one of atext? Yep. No consecutive periods? Yep.
What's the problem?
