I've tried next thing:
ssl = required
ssl_verify_client_cert = no
auth_ssl_require_client_cert = no
And began getting emails.
Successful logs attached. But i cant understand if data was passed with TLS.
How can i enable those 2 options "ssl_verify_client_cert",
"auth_ssl_require_client_cert" and get em working ?
