Mailing Lists and setting To: on new messages

[Ryan Phillips <ryan-mutt@xxxxxxxxxxxxx>]

Hi All,

What is the most elegant way to, within a folder, and on a new message set
the To: automatically for mailing lists?

I have

  folder-hook =list.mutt.dev "my_hdr To: mutt-dev@xxxxxxxx"

this works, but seems wrong.  Is this the preferred method?

Thanks,
Ryan
