Somewhat off topic but does someone here know if there's a standard file
extension that represents a null program. What I mean is that we rename
some attachment suffixes to .txt but this causes some problems with some
applications. We'd like to rename the attachments with another suffix,
one that will never be used for an application (present or future). Does
anyone know if a standard suffix has been created for just this purpose?
