mailing list missing "List-Post:" header

[Chris Bannister <mockingbird%earthlight.co.nz@localhost>]

Hi,

I use mutt as my MUA and usually 'L' allows a list reply but on this
list it says "No mailing list found."

Apparently it relies on a "List-Post:" header which is missing on this
mailing list.

Any chance of having one added?
