Yeah, that's obviously always going to be a problem with DKIM.
But I think all the kernel mailing lists are good now - at least
partly because I used to complain about it.
The one thing that vger still does - or at least did not that long ago
- is to change whitespace in headers. But that is perfectly acceptable
SMTP behavior, and it's a problem only when somebody is using
"c=strict/strict" in their DKIM setup. And honestly, that's a
completely invalid DKIM setting, I don't understand how the DKIM
people ever thought it was ok (probably some company politics or other
because some vendor was too incompetent to implement the proper
relaxed hashing).
