the alias were in this form
a1:	local!a2
a2:	local!a3

where a3 was a "real user."  the rewrite rules were standard,
except that the appropriate domain name was subsituted in.
someone had created /mail/box/a2.  this was the confusing bit.

isn't that that like saying /fd or /dev have no special
meaning in plan 9? the kernel may not care, but
convention is important.

mail -x a1 -> local!a2
mail a1 -> dead.letter (no /mail/box/a2/mbox)

so it's confusing that mailing a2 works but the a1
does not.  the problem is with my misuse of local in
the aliases, not with upas or the default rules.

although send could check mailboxes a bit more
carefully for deliverability.
