 * Whenever a comment is made in a certain post, I see few mails stuck in mail queue
   and never delivered. I guess few people (4) opted-in to receiving mails whenever
   a comment is made.

 * How can I solve this problem? The system tries to send this mail every x time
   I guess. I see lots of fails related to postfix in syslog file which probably
   overloads the server.

 * Hi [@radorp2p](https://wordpress.org/support/users/radorp2p/),
 * This probably comes from your mail delivery system. If you use some plugin for
   this you should contact the plugin support or your hosting support.

 * I don’t use any specific plugin. I’ve checked out the mail ID, it is PHPMailer
   which probably comes with wordpress itself. I don’t know how to fix it really
   now, it is unmanaged hosting.

 * Or how can I delete / disable subscription of these emails so that they will 
   be not sent again?

 * [@radorp2p](https://wordpress.org/support/users/radorp2p/),
 * We may suggest you remove the subscription in **wp_**wc_comments_subscription
   table in Website Hosting Service cPanel > PhpMyAdmin database manager.
 * If you never do it before, or you’re not familiar with the DB structure we don’t
   recommend you to do it. You may crash your website.
