Thunderbird:Returned Mail
Postmaster bounce mail is problematic for many people. The language that the Postmaster uses is difficult to understand and often it's not translated at all for the user viewing it.
At a minimum we should be providing an interface that removes Postmaster mail from the Inbox and allows it a special view all on it's own. This can allow us to help people in resending the message or understanding why it wasn't delivered.
Returned mail always appears new until it is deleted, ignored or resent. There is not read / unread state for returned mail.

Because there isn't always returned mail it makes the most sense to remove the mailbox item once a person has dealt with the returned mail.
In the returned mail list view we give options for resending, ignoring, or deleting returned mail. Once a person has removed the mail from the list view we can then remove the returned mail mailbox.
The removal of the mailbox is handled in stages, first showing that the situation has been handled by setting a zero count and normal font weight.
+----------------------+ | [+] Inbox | | [+] Drafts | | [+] Starred | | [+] Returned Mail | | [+] Sent Mail | | [+] Junk | | | | .................... | +----------------------+
Then we remove the mailbox from the list completely. A person can find these messages in future searches or in the Thunderbird:Activity Manager interface.
