Configuring TLS-enabled SMTP server for reports distribution

Hi Team,

I'm trying to figure out how to make Oracle Reports server work with a TLS-enabled SMTP server, if possible at all. It's been hours and I've been reading everything and its contrary. Here is my config in rwserver.conf:

<pluginParam name="mailServer" value="smtpserver.domain.fr">

      <property name="enableSSL" value="yes"/>

      <property name="port" value="465"/>

      <!--UserName and Password that can be used to connect to the mail server-->

      <!--property name="mailUserName" value="%MAIL_USERID%" /-->

      <!--property name="mailPassword" value="%MAIL_PASSWORD%"/-->

   </pluginParam>

I've tried with both ports 465 and 587 which are both enabled on the SMTP server, but I always get the same error in rwserver_diagnostic.log:
