We may have to disagree on this one. The way I read the standard, MDNs
first have to be requested with a Disposition-notification-to header.
Vacation notices are sent unsolicited, and as such, do not have a
disposition-notification-to style target, and thus the genesis of this
discussion, "where do we send the vacation notices"?
Now if you think that DSN applies to vacation notices, I will bring this
quote from 1894 up:

Now, I don't *really* think that DSN or MDN applies to vacation notices.
But Vacation notices are closer to DSN than to MDN since they may be sent
unsolicited, and I think that, in the absense of other guidance, they
should be sent to the transport envelope address and not the from or
