Hi folks-
 
Please pardon what to most of you is probably a pretty basic question,
but I am receieving regular delivery failure notices (error 550: user
unknown) for a user who I cannot find in a regular REVIEW command. I
have already tried to DEL this user, but listserv says he isn't a
subscriber (I can't find even a significant substring of his address
in the REVIEW output).  How can I check what CONCEALED users are on my
list?  Thanks.
