- There are several places where 'folder' and 'mailbox' seems used interchangeably in the doc and could lead to confusion. Need to pay more attention on subsequent edits.
A mailbox can have multiple folders. I'll see if I can make that clearer.
- The doc stated that using A-label in mailto: will shorten the whole string, which sounds like an encouragement. I'm concern on that.
I don't feel strongly about it. I would expect addresses to work whether the domain is encoded as U-label or A-label.
- I would love to see more write up regarding spam filtering, particular on determining whether certain character is valid or not (even calling it out of scope for this doc), and to raise awareness that detection algorithm may detect downgraded message as suspicious/malformed/etc.
It shouldn't. Remember that UTF-8 is already valid throughout message bodies, and propertly downgraded headers are all ASCII. R's, John
