As far as i've understood your issue, your gateway allows SMTP out for all hosts but HTTP for a few hosts. So you want all hosts to be able to send HTTP out. As far as i understand stunnel, you need to have it installed on both machines -- the computer inside and one outside. The computer outside would be running stunnel on the SMTP port so when connecting from inside, it appears to your firewall like you are transmitting to the SMTP port. Otherwise IMHO stunnel may not be for your problem. You may need to touch your gateway/proxy. ------------- Brian
