The outside mail will still have to come to the machine with the public address - so it must continue to run sendmail. This machine could forward the mail onto another machine with an internal address. Use the virtusertable to redirect the mail to a private name and put the private name MX in your DNS. You may even be able to put a line in you virtusertable like: *@mypublicdomain.com *@192.168.30.4 This would avoid any internal MX line. not sure that's legal.
