Please note: with the CURLOPT_HTTPPROXYTUNNEL option still in place, I am

However, when I connect to an external mail server (such as gmail), I get
the following logs:
* About to connect() to smtp.gmail.com port 465 (#0)
This looks wrong as libcurl here tries to connect to the remote host and it
seems you want to use a proxy. You're supposed to have entered a proxy as
well, as CURLOPT_HTTPPROXYTUNNEL only changes how it uses the specified (HTTP)
proxy. You need to provide the proxy name and port separately.
* Trying 173.194.68.108... * Connection refused
... clearly you can't connect directly to these hosts on port 465. Nothing
libcurl can do much about!
