In seems to me that we must agree on what content is allowed in the
decoded scheme specific part of an instant inbox URI.  From your
discussion, it appears that I got the description wrong!  I made the
assumption that all instant inbox URIs are opaque, but the following
URI seems legal after all:

        im://mitre.org/[email protected]

since "//mitre.org/ramsdell"@ninebynine.org is a valid email address.

Let me try this definition instead.

  URI u is an instant inbox URI if and only if all of the following
  are true:

        * The scheme of u is the string "im".

        * There exists an RFC 2822 email address e such that the
          decoded scheme specific part of u is identical to e after
          all invisible characters in e are removed, using the RFC
          2822 definition of an invisible character.

        * The fragment part of u is absent.
