It's even uglier than that: some sites will interpret a%b@c differently than
b!a@c, even if they both give @ highest priority; experience probably told
David to write henry%utzoo.uucp@uunet.uu.net instead of henry%utzoo@...  On
some networks the second address may have been interpreted as henry on "the
local utzoo", as opposed to the utzoo you will find in the uucp maps.  We have
live confrontations like that every once in a while (when the person meant the
physics machine on the UUCP net and got our department of physics, our
vice-versa).
