They do.  If they're not hallucinogen-positive, the RFC gets rejected
without comment [sic].  I think this is Dan Bernstein's problem.

Actually, under normal circumstances, the stuff in RFCs is intended to 
make it easy to verify that a computer program recognizes exactly the
legal cases and spits errors for illegal cases.  Normal use is rather
simple, the exceptional cases are usually introduced for (a) backward
compatiblity or (b) human consumption.  Type (b) exceptions are what
make RFCs hard to read, they are invariably impossible to express
without a full-blown expert system.  :-)

Those aren't (Dmytro explains), but

    "darren@example.com"@example.com
    darren(@example.com)@example.com

are.  (Of course, it's highly unlikely that your sysadmin would let you
have an alias like that. ;-)

Answer to exercise.

To write a compu$erve address with a comma, you must do something like

    "12345,6789"@example.com

because comma is the address list delimiter.
