How to not disable the showing of hostname in message-id?

[Peng Yu]

Hi,

I set `hidden-host` to yes. But the hostname still shows up.

http://www.mutt.org/doc/manual/#hidden-host

I don't want to use the following solution as it still shows the
hostname even it is fake.

Could anybody let me know if there is a way to disable the appearance
of hostname in message-id? Thanks.
