# Reason and fix for "Domain has exceeded the max defers and failures per hour"

## "Domain has exceeded the max defers and failures per hour (5/5 (26%)) allowed. Message discarded."

There are three major reasons for this message:

* Exploited or hacked sites sending out spam emails. A few customers who send out mass mailings have been triggering this feature, due to the number of bad/undeliverable email addresses on their lists.
* The disk quota for the email account/domain has been reached and new messages are being deffered.
* There is no such email account created on the mail server.

### SHARED LINUX (CPanel):

If you are on a Shared Server (cPanel) server, in case your account is infected please open a TICKET to our Technical Support. This way our technical team can investigate for infections and reset your limit. If you have installed some of the more popular CMS (Worpress; Joomla...), you can proceed and review this [ARTICLE](https://clientarea.mochahost.com/knowledgebase/582) on how to clear your application of infections.

**If your disk quota is reached, please follow the steps below:**

1. Login to your Cpanel.

If you are getting a non-existent email account, please make sure that your Mail Exchanger is set to  Local server by us following this [TUTORIAL](https://clientarea.mochahost.com/knowledgebase/709). Otherwise just create the missing email account from your Cpanel following this [TUTORIAL](https://tutorials.my-virtual-panel.com/cpanel_paper_lantern_end_user/create_email_account.html).

### VPS/Cloud LINUX (CPanel):

Note: To reset the limit per domain you need to remove the following file via root Shell access:

`rm -f /var/cpanel/email\_send\_limits/max\_deferfail\_domain.com`

*  domain.com = the domain where your messages are deffered
