    Hi

    I am facing the same problem but repair mail doesn't work.

    I have installed let's encrypt on webmail, and since then I can't send email using PHPMailer (SMTP connect error)

    maillog says :

    SSL_accept error from localhost.localdomain[127.0.0.1]: -1

    warning: TLS library problem: 27872:error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:640:

     lost connection after STARTTLS from localhost.localdomain[127.0.0.1]

     

    it works fine on another server on which I didn't secure webmail. So I think the problem comes from let's encrypt
