* Use one and only one charset (my advise: utf-8)
so you don't want people to be able to send documents that happen to be written in other charsets? or you want to force them to translate, sacrificing transparency?
* Use one and only one content transfer encoding (my advise: 8-bit)
so you don't want binary transparency?
I would like to have a header specifying the jurisdiction the email is sent by.
absent some way to authenticate that information, I'd simply claim that the mail was sent from the jurisdiction with the least restrictive rules.
I expect spam to be a non-issue in mail-ng, but having a jurisdiction header would make it easier to drop messages violating local laws
nah, the spammers would just move to some other country.
Filtering based on the ISO Country Code List would be much easier than keeping a list of IP ranges up to date.
the last thing we need is to encourage more stupid spam filters. see http://www.cs.utk.edu/~moore/opinions/spam-filters.html
