Hello,
I'm using Postfix 3.3. I am atempting to send mail from a remote
android phone running AquaMail Pro, which does support ECC
certificates of secp-256. So I got an ecc cert pair from letsencrypt
and installed it. Atempting to send an email gives me a handshake
error on the android client and the below log output, also my postconf
-n output.
Suggestions welcome.
Thanks.
Dave.
