What is Mail Queue?
Mail Queue is a directory in SMTP Server that stores data and controls mail messages that delivered by sendmail command. Mail queues are formed when the SMTP server has many email messages queued up waiting to be delivered, to avoid sending too many messages from the same server at once – which can cause IP reputation issues. WHM allows you to manage the mail queue on your server and perform actions such as forcing delivery, removing emails from the queue, or checking the email content.
First, log in to the WHM control panel.
Next, navigate to the Mail Queue Manager section.
You’ll now see a list of all emails currently in the mail queue, as long as a search tool for searching through emails that are in the mail queue.
Removing emails from mail queue
From time to time you may wish to remove emails from the email queue, for example, if they’re troublesome or unnecessary.
To remove an email (or multiple emails), from the email queue, first of all, find the email you wish to delete, and then click the tick box beside it.
Finally, click Delete Selected to remove the emails from the mail queue.
Delivering emails from mail queue
Emails will be automatically delivered from the email queue after a certain amount of time, however, you can manually force delivery of specified emails from the mail queue as well.
As before, locate the emails you want to deliver, and then tick the tick boxes for them.
Once you have the emails selected, click Deliver Selected to attempt delivery for those emails.
