Subject: [9front] [PATCH] nedmail: only display most useful headers
Reply-To: 9front@9front.org
Precedence: bulk

Hi,

Below patch limits the headers displayed by nedmail to the most "useful"
ones:Date, From, To, CC (is set) and Subject.
This helps with some mailing lists or mail providers adding loads of noisy headers.
This only applies to the 'p' command and all headers are still visible
when using the 'P' (display raw) command so nothing is lost.

cheers
