And then, of course,  there were the bright ideas about
universal/ global email directories.  One hesitates to describe
where those went  :-(

PS: There have been some attempts at setting up
change-of-address services where you can register old and new
addresses, so mail servers could query them after getting a
550, and they never went anywhere either.

See US Patents 6,654,789, 6,892,222, and 7,080,122.

By the way, 6,654,789 expires a week from Monday and 6,892,222
expired last year so if you find any good ideas in them, you
can use them.

7,080,122 doesn't expire until 2023.
