Notifications to detect spoofing if posting by email
It's possible, though unlikely, for someone to spoof posts from you by email. Notifications would help people recognise if/when this happens.
This one's a bit out there, but it came up in discussion about replying to comments by email, so I'm posting it as a suggestion.
Currently you can post by email from any of a list of registered email addresses. You also need to use a PIN to post. However, if someone knew your email address and could guess your PIN, it would be possible for them to spoof your email and post as you.
I therefore propose a notification setting: "notify me when I post by email". This should go to your primary registered address and basically just say, "We received an email post from address firstname.lastname@example.org, here's a link to it."
As well as being a warning if someone's spoofing you, it could also just be a good diagnostic to make sure your posts are getting through, if you don't have web access. Which after all could be a big part of why you're posting by email in the first place.
(You could make the setting be a bit cleverer, if you wanted to, by offering options like: "Notify me when I post by email: always, if spoofing is suspected, never". The "if spoofing is suspected" could be based on various things, but the obvious one that comes to me is <a href="http://en.wikipedia.org/wiki/
Should be implemented as-is.
