No.

But it could say "invalidated" if there is an immediate error return
mail.

But even that is not altogether trustworthy, since E-mails can be
rejected, perhaps immediately, on grounds other than address. I auto-
reject any mail *from* merlyn, since I know none is sent and some is
forged.

I lease all of merlyn demon co uk and dial up occasionally.

Mail for *@merlyn.dcu will be held at Demon until I next connect; and
cannot be rejected until then. If I were to alter my settings to
collect only mail for legitimate names, mail to others would be returned
by Demon after 30 days.

If I were on broadband there would still be a small delay, a few
minutes, I think.

While not connected to the Internet, I can change the list of addresses
valid at merlyn; and no-one can detect that from outside this room,
until I next connect.
