  Eeeesh.  Yah.  I regularly remind my clients that Internet email is not
and never was a "guaranteed reliable" service, and that if the subject
matter is critical, one should follow-up email in some way (such as by
sending a fax, or requesting positive confirmation of receipt *from the
person* (and not their mail program)).

  Not that many listen, but at least I've warned them.  :-)

  Indeed.  That's my objection to dynamic range blocking.  (IMNSHO, you
shouldn't be trying to run an MX on a dynamic address, ToS violation or no.)  
But AOL seems to block mail more or less at random, and any attempt to get
them to explain or change their ways is futile.
