I've got one better.  One of my customers in the Tampa area uses a
business static RR connection to host their in-house email server, and
they could not send in to anyone @tampabay.rr.com.  Evidently the powers
that be at RR security blocked one of their own subnets.  The reject
statements cited our class C subnet, which is wholly theirs.  D'Oh!!!

Never did get 'em to fess up about what was wrong.  Just started
magically working.
