Hi
I have question, because I was not able to find answer anywhere on internet.
I started to use Stunnel in server mode to provide POP3S/SMTPS functionality. Everything works fine except that I am missing remote IP of connecting client.
I am using Windows version so I can not use transparent proxy mode working on Unix.
Is there way how to make Stunnel for example after each establishment of TCP connection to send to SMTP/POP3 server port some special command like
REMOTEIP 123.123.123.123<crlf>
to pass this information there. I know it is not in SMTP/POP3 standard but it is simple for me extend behavior of SMTP/POP3 service by this command?
Thank you very much for any advice
Zdenek

Good news: This feature is already available in stunnel since version 4.45.
To enable it add the following line to your stunnel.conf: protocol = proxy
