No, TLS encryption is not available between the SMTP server and
the pre-queue proxy filter. To use TLS for content inspection the
only option is the post-queue content_filter. If filtering needs
to happen before the client disconnects, I'm afraid TLS is not
possible.
TLS client functionality is not available in the Postfix SMTP
server.
