ISVW can be configured an used in severall ways.
1.) as the primary listener for mail which then forwards mail to your sendmail/postfix/whatever...
2.) as a plugin to sendmail
3.) in a "sandwich" way: recieve mails with your favourite MTA, forward it to ISVW, use second instance of your favouriter MTA to deliver mail....
