In my remote_smtp transport I have:
hosts_require_tls = <; fc00:beef:beef:601:9530:2068:3df9:5cb7
I just added this to the top of my rcpt ACL:
warn control = cutthrough_delivery
Now I'm getting this in my mainlog whenever a message is delivered:
2013-10-30 12:16:18 a TLS session is required for hype.glue.grepular.com [fc00:beef:beef:601:9530:2068:3df9:5cb7], but an attempt to start TLS failed
The message *is* delivered using a TLS secured connection though:
