SNDDST Failing with DIA Error 0401

["Coleman, Katherine" <KColeman@xxxxxxxxx>]

Trying to do a simple SNDDST with a text file attached and am receiving the
following error.  after a detailed dreview of the SNDDST command, referring
to several online articles and lots of trial (and continued error), I still
cant figure out what is wrong.  My command is very simple, and I get the
same error no matter what I try to send - .TXT, .DOC .XLS - or who I try to
send it to.  A SNDDST *MSG works fine and lands in our mailbox nicely, but
now I want to attach a document. 

Any advice greatly appreciated.
