I have done this twice before and now my list won't let me.
I am sending listserv
 
QUIET ADD newsletter DD=X IMPORT
//X DD *
(1600 email addresses one line each)
/*
 
After sending back my ok confirmation, listserv sends a message saying
> QUIET ADD newsletter DD=X IMPORT
DDname "X" not found in job stream.
 
What does this mean and what am I doing wrong?
