Userid used to deliver usenet articles to newsgroup folders (usually via
lmtp2nntp).  For example, if set to "post", email sent to
"post+comp.mail.imap" would be delivered to the "comp.mail.imap" folder.

When set, the Cyrus NNTP server will add the header(s) specified in the
:imapdconf:`newsaddheaders` option to each incoming usenet article.  The
added header(s) will contain email delivery addresses corresponding to each
relevant newsgroup.  If not set, no headers are added to usenet articles.
