I posted this some time ago, and since I've done a few tests and still have a problem receiving emails from a chatter thread in my emails.

I'm testing on Leaves. I've subscribed as a follower of a Leave object. In my user settings I've set "All Messages (discussions, emails, followed system notifications)".

When a user creates a new message using "Send a message" at the bottom of the Leave Request, I receive a message in the "Messaging/Inbox" form, but I don't get any message via email. I've looked in "Settings/Email/Emails" and there is no email in there, so I think the Message doesn't get transformed to an Email. Indeed, I can see the message in "Settings/Email/Messages".

Any ideas ?
