Description:
Discover why your domain exceeds the error limit per hour and follow these steps to fix it easily.
What will you learn here?
If you've received a message that says:
"Your domain has exceeded the maximum number of bounces and errors per hour"
don't worry — it's a fairly common notice. In this article I'll explain what it means, why it happens and how you can resolve it step by step so your website and emails keep working without interruption.
What does this message mean?
The server is telling you that too many errors have occurred when sending emails in a short period of time (usually one hour).
These errors are called bounces, and they occur when emails don't reach their destination for reasons such as:
Wrong email address.
Recipient's mailbox is full.
The destination server rejects your email (possible spam filter).
Why are you temporarily blocked?
To protect your domain's reputation and prevent it from being used to send spam, the system limits sends when it detects many failures in a short time.
How to fix it? Step by step:
1. Review bounced emails
-
Access your DirectAdmin or cPanel control panel.
-
In the Email section, go to Track Delivery.
-
There you'll see the failed emails and the reasons.
Error example:550 5.1.1 User unknown — This means the email address doesn't exist.
2. Identify the cause
-
Are email addresses misspelled?
-
Does the recipient have a full mailbox?
-
Has your domain been blocked for spam?
Check the specific error messages to know what to correct.
3. Fix the detected problems
-
Make sure your recipients' addresses are correct and up to date.
-
If you use mailing lists, clean them by removing inactive or non-existent contacts.
4. Control the quantity and frequency of sends
-
If you send bulk emails (newsletters, notifications), do so gradually or use specialized tools that respect the limits.
