Konstantin Ryabitsev has a
request for anybody who is using mutt for kernel work:

At some point in the recent past, mutt changed the way it generates
Message-ID header values. Instead of the perfectly good
old way of doing it, the developers switched to using
base64-encoded random bytes. The base64 dictionary contains the
/ character, which causes unnecessary difficulties when
linking to these messages on lore.kernel.org, since the /
character needs to be escaped as %2F for everything to
work properly.

The post includes a simple workaround for the problem.
