If you notice potentially suspicious activity on your email accounts, such as sending out a large number of emails or receiving repeated messages from the same sender, you may want to suspend incoming and outgoing emails to prevent your email accounts from being disabled or flagged for abuse.

To change the sending and receiving settings of an email account, log into your cPanel, head to the Email section, and select Track Delivery:

You can also reach this option by typing it in the search bar. In this section, you will find the Delivery Report table. It will only show Failures by default - you can select to display also Successes, Deferred or In-Progress messages.

To check the delivery event details, click on the Actions icon:

This information will help you determine whether any email account should be suspended. To suspend an account, go to Email → Email Accounts:

Click on Manage next to the email account you want to suspend and scroll down to the Restrictions section. Once there, change the Sending Outgoing Email status to Suspend. This will prevent your account from sending out emails:

You can also choose to suspend the Receiving Incoming Email to stop receiving emails from any sender. When all is good to go, click Update Email Settings to enable this configuration. You will see a pop-up notification confirming that the configuration is now applied to the email account.

Alternatively, if you no longer need the account, you can also delete it in this section by clicking on the Delete Email Account button.

To resume receiving and sending emails again, simply navigate to the Restrictions section of the desired email account and select the option Allow under Receiving Incoming Mail and Sending Outgoing Email. Make sure to click the Update Email Settings to apply the changes.

That’s it! Now you know how to suspend and unsuspend email accounts in cPanel.
