I am looking at stunnel as a way to add SSL/TLS to an SMTP server, but my issue is that the SMTP server must be able to determine the address of the incoming connection to perform RBL checks, reverse MX record checks, PTR checks, etc. From what I can understand, however, the SMTP server will only see the client side of the pipe (localhost) as the originating address, instead of the originating machine IP.
That is how a proxy is expected to work.
Is there any way to get the SMTP server to see that original IP address? Or baring that, is there anyway that stunnel can insert a header into the mail indicating the original IP address?
I know there are some people that implement it based on log files.
What is your SMTP server? Why don't you use a native SSL support?
Are there really a lot of spammers that use SSL to send spam?
