How to pass remote IP to local SMTP/POP3 server
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 ____________________________________________________________ FREE 3D MARINE AQUARIUM SCREENSAVER - Watch dolphins, sharks & orcas on your desktop!

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 Protocol description: http://haproxy.1wt.eu/download/1.5/doc/proxy-protocol.txt Best regards, Michal Trojnara
