[stunnel-users] outgoing mail solution?

[Josealf.rm]

I think your only option is to run a full MAil Transfer Agent (SMTP server) on your XP. you can configure it to accept non authenticated mail on 127.0.0.1 and to forward your mail to gmail with authentication. I just checked and there is a good free open source candidate: hMailServer.
