integration of Netscape and p..

hi,
 actually i wanted procmail to put my mails in my nsmail directory(Netsca
 pe mail directory). The mails should be put in the files corresponding 
 to the sender in the nsmail directory.

 THE PROBLEM
-------------
  the mails come fine.
  but after deleting the mails inside netscape. the mails resurface if
  a new mail arrives in that folder.

 Help me out.
 In Anticipation of a solution
  Sorry if my question is too trivial, coz i really couldn't
  figure out a solution.

Thanks
 Jaikant
