-The draft says:
-
-     Vacation responses are not just per address, but are per address

-This is badly worded, because commands are not enumerated.  It meant
-to say:
-
-     Vacation responses are not just per address, but are per address
-     per reason string and per specified subject and ":mime" option.
-
-Existing implementations work that way and it makes more sense, too.
-Including the ":mime" option is mostly for correctness, as the reason
