[Alessandro Coppelli <coppelli dsea unipi it>]

  Sorry for newbie question .

  I want to install a POP3 server but the problem is :

 how I must to do for passwd ( Netscape use SSL ;
 Eudora passwd,kerboros,APOP ; Outlook ....  ) .

  I want get qpopper and install it with protection for passwd but
  which are the options ?

  Is there  a one cript system for this client (Eudora, Netscape and
Outlook. ) ?
