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>
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
