Topic: SSL/TLS issue
Hello,I'm using your Email Store/Forward service and like it a lot. However, I have this mail delivery issue when using TLS on my mailserver (Postfix 2.11.7).I have a certificate for my domain (including the mailserver subdomain) signed by Let's Encrypt. When I set Postfix to use TLS, turn on SSL/TLS connection security in your web interface and save the settings, I get this error when your server tries to deliver messages:SSL_accept:failed in SSLv3 read client certificate ASSL_accept error from mail.dynu.com[63.141.230.148]: lost connectionI only get this error with your server however. I can relay emails from my other machines on LAN (TLS without authentication) or from SASL-authenticated (and TLS-enabled) clients from anywhere with this setup. When I disable TLS on my server and in your interface, emails are delivered without a problem.After some searching I found this happens when server doesn't trust the certificate. Isn't Let's Encrypt among your trusted CAs? Or is it something else? I would really like to have this connection secure.Thank you,Petr Hejl
