#21 generate signature based on List-Id header

[Jason Long]

Dear Jason,

Thanks muchly for your help. I spent some more hours but could not
solve the issue.
BTW, I have a friend who is running some dozen of mailing-lists also,
so we both need this signing feature based on List-ID's domain with
both DKIM and Domainkeys.
We think this feature would benefit a lot of people running mailing
lists around the world. As long as you are very kind to provide the
software as opensource. We'd like to ask if you have time/interest to
make a new feature available in dkimproxy? For example add a
configuration parameter (--addon-header=list-id) that tell dkimproxy
to sign emails based on the domain specified in the addon-header
field.
We'll be very happy if we can show our gratitude by donating money or
resource to the project, show the links to dkimproxy in our websites
and recommend our friends (for example FreeBSD community) to use
dkimproxy.

Please kindly let me know your opinion.
