Domain (example.com) has exceeded the max defers and failures per hour Print

  • 0

If you are receiving an error similar to "Domain example.com has exceeded the max defers and failures per hour (5/5 (100%)) allowed" in an email bounceback, it means that outgoing email from your domain has triggered a rule in the server that will stop any further email from going out of the server. This happens when a domain account sends out emails that either fail or get deferred. If the number of failures or defers is greater than the server limit, no further emails will be processed.

This error is generated by an hourly monitoring system, where any blocked domains are allowed to send email again at the top of every hour. For example, if you received this error at 1:15 pm, the block will release at 2:00 pm and the domain will be able to send emails out once more.
