I am unclear on why webmaster at sf-lug.org being a valid mailbox
necesarily means that webmaster at lists.sf-lug.org becomes automatically a
valid mailbox.  I might be missing something, but it seems to me that
all modern MTAs are capable of doing virtual domains, with separate
namespaces, correctly.

Anyway, not my problem.  ;->
