I suspect that you need to make an unsecure connection to the proxy first,
and then encrypt the data afterwards.

That will disable SSL and establish an unsecure connection initially. You
did not say how you have the TIdSMTP configured, though. If you are not
already doing so, you should set its UseTLS property to utExplicit. That
way, TIdSMTP can use the STARTTLS command to test the SMTP server's ability
to support encryption and then to establish a secure tunnel only after the
initial connection has been established.
