Re: Intended policy changes for mailing list setup

Dear Erik & all involved,

a big THANK YOU for your work on this, and for so clearly describing
the changes.  Personally I'm very happy about them - not just because
they increase the chances of mail going through, but also because the
new configuration just looks cleaner to me.  (I like as much
end-to-end transparency as I can get :-)

Best regards,

>  * Adding the e-mail footer may invalidate the e-mail's DKIM signature

> Due to the above, we will change the mailing list setup for all mailing lists:
>  * No longer add the mailing list subject prefix
>  * No longer add the mailing list footer
>  * Add the List-* headers as per RFC-2369,
>    filtering of mailing list messages can be done using these fields
