Hello Eric et all,

Just for the record, i have verified it twice with two boxes.

- install QMT as usual with Roundcube
  Stock CentOS7 install PHP 5.4 and  roundcubemail-1.1.12-2.el7.noarch

  WebMail RoundCube works perfectly.


- Follow http://www.qmailtoaster.net/roundcube.html in order to use Carddav

  Remi Repo upgrades:
  PHP 5.4 to PHP 7.1 as desired.
  and  roundcube 1.1.12-2 to roundcubemail-1.3.9-1

  After the installation,  Roundcube webmail fails when sending with an
  "SMTP Error (220): Authentication failed."

 Enabling roundcube debug, you can see lines like this:

  ERROR: STARTTLS failed ()
  ERROR: Invalid response code received from server (-1)
<e05a7e10> SMTP Error: Authentication failure: STARTTLS failed (Code: ) in /usr/share/roundcubemail/program/lib/Roundcube/rcube.php on line 1673 (POST /email/?_task=mail&_unlock=loading1562266704995&_lang=en_US&_framed=1&_action=send)

- Problem is solved only if add the following in my

  $config['smtp_conn_options'] = array(
  'ssl' => array(
  'verify_peer' => false,
  'verify_peer_name' => false,

I wonder if this is the correct approach and if any else is dealing or can reproduce this issue at least.

kind regards,
