 * I’m using WP 4.9.1 and PHP 7.1.x (latest).
 * For me the plugin doesn’t work at all.
 * > PHP Deprecated: Function mcrypt_get_iv_size() is deprecated in /home/wp-content/
   > plugins/smtp-mailing-queue/classes/SMTPMailingQueue.php on line 433
 * same for line 434, 436, 452, 453, 455
 * Also
 * > PHP Deprecated: Non-static method SMTPMailingQueueAttachments::storeAttachments()
   > should not be called statically in /home/wp-content/plugins/smtp-mailing-queue/
   > classes/SMTPMailingQueue.php on line 234
 * So clearly this plugin is NOT compatible with WP 4.9.1 as you mention in your
   description.

 * Hi dimalifragi,
 * The messages you get are deprecation notices and are far from fatal errors. They
   also have nothing to do with the WordPress version.
    Deprecation notices simply
   state that in future PHP version the used functions or features will be removed.
   Using them in PHP 7.1 doesn’t break anything and just tells you to consider updating
   the code to make it future-proof.
 * If you are seeing deprecation notices in a production site I recommend adjusting
   your error_reporting level (see [https://www.php.net/manual/en/function.error-reporting.php](https://www.php.net/manual/en/function.error-reporting.php))
   and/or the error output ([https://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors](https://www.php.net/manual/en/errorfunc.configuration.php#ini.display-errors)).
   Check [https://phptherightway.com/#error_reporting](https://phptherightway.com/#error_reporting)
   for good practices regarding error reporting.
