A wildmat pattern specifying which mailbox hierarchies should be treated as
newsgroups.  Only mailboxes matching the wildmat will accept and/or serve
articles via NNTP.  If not set, a default wildmat of "\*" (ALL shared
mailboxes) will be used.  If the *newsprefix* option is also set, the
default wildmat will be translated to "<newsprefix>.\*"
