I leaped before i looked again!  My server has an irritating habit of
delivering a message, then telling you it couldn't do it, even though it
already has.  So, when a failure message telling me something called
"aardvark.com" (i kid you not!!)  couldn't deliver my "how to" message,
i immediately re-sent the thing, before checking my trusty Conch-digest
to see if my server was lying.  It's a jungle out there in cyber-land!!
