In some future release, would it be possible to specify an address to
which all items trapped by IGNORE= or FILTER_ALSO= would be sent ?
( If addr-keyword= <null>, process as usual - i.e. bitbucket )
 
( would take worry out of wild-carding and allow counts of nuisance
  posts - but going to somewhere other than postmaster or the LISTSERV
  maintainer so they can be checked on a time-available basis )
