[stunnel-users] Help With Verify = 3

Hi,

I installed Stunnel 4.12 on a Linux box, and am attempting to use it to secure SMTP e-mail injection from Windows machines.

I have everything working, and I have a Windows Stunnel client which will inject mail into a Linux Stunnel server over TCP Port 465.

However, I've been unable to find the right combination of verification settings to cause the server to refuse connections from clients without the right certificates. Right now, I'm able to inject mail if the client has ANY certificate.

Is there any tutorial on how to generate the keys, .PEM files, and the Stunnel settings to have the behavior where only MY clients can inject mail?

Thanks and best regards, Dave Ashley.
