Hi

Since I upgraded to OpenBSD 5.9 (I think) I've been getting TLS
validation errors in the headers:

        TLS version=TLSv1.2 cipher=ECDHE-RSA-AES256-GCM-SHA384
bits=256 verify=NO

Prior to the upgrade I would get verify=YES. (I think it was the
upgrade to OpenBSD 5.9 and whichever OpenSMTPD that comes with it that
did it - it was certainly about that time)

I have now upgraded OpenSMTPD to the current 5.9.2 release and that
makes no difference.

All logging suggests that cert validation is OK (though I note that I
only ever get that message on outgoing lines, and never on incoming)

What does OpenSMTPD use as its default cert store - as far as I can
tell the .conf lacks CAfile or CApath options?

Testing with openssl s_client suggests that my certs are generally in
order

Any clues?

Many thanks

John Cox
