    Hello,

    After upgrading to 1.0.0 (and then 1.0.2) from 10.1, we are experiencing issues with SMTP authentication. Another environment that is still running the 10.1 version of the plugin is without this issue. The credentials haven’t been touched.

    Attached is the error log:

    There was a problem while sending a test email.
The related debugging output is shown below:

    Hey aaylersghost,

    Thanks for reaching out!

    In 0.11 and 1.0, we disabled SMTPAutoTLS because it was giving some users issues. However it now seems that doing that causes issues for other users.

    When you get a chance, the code snippet below should resolve the issue, if this problem is indeed caused by the changed SMTPAutoTLS setting. It should go in your site’s functions.php file or similar.

    
function wpmailsmtp_enable_autotls( $mailer ) {
	$mailer->SMTPAutoTLS = true;
	return $mailer;
}
add_filter( 'wp_mail_smtp_custom_options', 'wpmailsmtp_enable_autotls' );

    What we’ll likely be doing is releasing an update in the coming days that changes the default of this setting back enabled, then provide an option in the setting to easily disable it for those users that experience issues. This way the setting is flexible and users can see which works best for them.

    Hope that helps! Thanks for your patience 🙂

    hi @jaredatch, thanks for the prompt response. i’ve applied the filter and all’s good.

    looking forward to seeing this as a setting option in the near future!

    best,
