Hello,
you cant use port 465, please use port 25. The SMTPS is ancient and not support via proxy protocol. Iam refering to your listen port.
you may remember me asking after this a month ago. PROXY protocol + tls wrapped mode in postfix not working was a bug and is fixed in the latest postfix release (and backported down to 2.9): http://www.postfix.org/announcements/postfix-3.0.3.html Of course, this release, being merely three days old, has yet to propagate to distributions. Best, Luke
