I have a list owner who sends out a weekly newsletter and for the last few
weeks has every sprint.ca e-mail address on her list bounce with the
error below returned.  sprint.ca says it is Listserv's fault
because sprint.ca is in capital letters and their machine is case
sensitive.  Makes no sense and a smtp dilague can't be duplicated to
create the error with sprint.ca.  Any ideas as this one has me stuck
(note the 553 after DATA)?
