From what I can see in the forum archives, the mail/imap proxy does not support encrypted connections to a backend imap server. This still appears to be the case with the latest mainline version. Are there any plans to add that? It would be really great if our nginx imap proxy server could talk to our imap servers directly over a secure connection and not require stunnel or some other work around.

Additionally, it would really help us out with a current issue we are facing. We would really like to be able to proxy imap connections for some of our users to imap.gmail.com and to our local imap server for other users. However imap.gmail.com only supports a secure imap connection and testing with stunnel still fails ( we get "upstream sent invalid response" error ). Has anyone successfully gotten nginx to proxy imap connections to imap.gmail.com? If so, I would really like to hear how you did it.

The flexibility of nginx as an imap proxy has been wonderful and having it be able to talk to imap.gmail.com and do ssl would make it that much more amazing.

Thanks,
Dan
