I really have to agree with Dave's observations above. The challenges we
face
are more related to properly setting the expectations of the end users than
with actually getting the message delivered. They tend to view SMTP message
transport throughout the entire Internet as equal to the internal transports
among our various offices. These users have no conception of the
differences
between locally connected recipients and dial-up recipients. On the one
hand
we have done our jobs extremely well and made Internet E-mail look
virtually identical to internal E-mail. In MOST cases the differences are
negligible. The times we run into problems are when a message is lost, or a
bounce
message is improperly addressed due to some problem with the user's MUA and
it
never gets delivered to the end user. These are issues that are not easily
addressed in working groups and RFCs.
