 * After the latest update I receive the following error from Postman SMTP plugin:
 * Postman: wp_mail has been declared by another plugin or theme, so you won’t be
   able to use Postman until the conflict is resolved.
 * This is caused by including pluggable.php in your plugin which causes conflicts
   with other plugins trying to redeclare function from there. Please advise.

 * Thank you for letting us know. I’ll investigate what can be done about this and
   will try to have a solution later today.

 * We have released version 4.3.9 that no longer uses pluggable.php which should
   resolve the conflict.
