In some email-clients, when you copy the Message-ID to the clipboard
it surrounds in (or perhaps, doesn't strip) angle brackets.
When pasting this into the mail archive search, search fails to find the message
and this happens often enough so as to be annoying. The fix is trivial.

Discussion of similar problem in the commitfest app:
