 * Hi, we are using mailpoet for internal use only to provide new blogposts to our
   employees.
    Since the last update (wordpress: 6.0 and Mailpoet: 3.89.3) there
   is an error when trying to send via our internal mail server. We do not use SSL
   for our internal mail server so i set the “secure connection” to “no” and “Authentication”
   also to “no”.
 * When i try to send a test email i got this error:
    `SMTP Error: Could not connect
   to SMTP host. Connection failed. stream_socket_enable_crypto(): SSL operation
   failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:
   certificate verify failed
 * Before i updated wordpress – everything works fine.
    Can anyone help?

 * We are having the same issue since we updated to WordPress 6. In our case, our
   email server is not secured, but using SMTP autentication. It’s a secondary server
   located in a subdomain we use for sendig newsletters. We are getting the following
   error:
 * El correo electrónico no pudo se enviado:SMTP Error: Could not connect to SMTP
   host. Connection failed. stream_socket_enable_crypto(): Peer certificate CN=`*.
   srv.cat' did not match expected CN=`newsletter.xxxxxxx.com’.
