There can be multiple reasons why an email inbox constantly receives messages with the subject “Mail delivery failed: returning message to sender”. The most common reasons are:
1. The email inbox sends SPAM messages
- To resolve this issue, you need to reset the password of the affected email account. If you are using cPanel, you can follow the guide: Reset password of email account in cPanel.
- It is also recommended to scan all devices from which you access this email inbox using updated antivirus software.
2. The website's contact form generates SPAM messages
- If you have a contact form on your website, it may be the target of robots that generate SPAM.
- To prevent this behavior, we recommend implementing a CAPTCHA module on the contact form.
