As for a practial limit ... good question! I would guess that anything
over a kilobyte would be asking for trouble.
The RFC 5322 limit of 998 characters (excluding the trailing CRLF)
in a line would apply here, I believe. A variable amount of that
would be available for the display name, taking into account the
field name, punctation, and the real address(es).
