Overview
If you are experiencing repeated access issues to your mailbox, such as being blocked from sending or receiving emails, it is likely that a misconfigured device on your network is causing repeated failed login attempts. This results in your public IP address being temporarily blocked by our server’s firewall.
Symptoms
You are unable to access your email.
You receive an error message indicating your IP address has been blocked.
You need to manually unblock your IP by visiting the URL provided in your email hosting control panel repeatedly.
Possible Causes
An incorrectly configured email client (such as Outlook, Thunderbird, or a mobile mail app) is attempting to log in with incorrect credentials.
A device on your network is making multiple failed login attempts.
Incorrect email password stored in one or more of your devices.
Outdated mail settings in your email client.
Too many devices attempting to check mail simultaneously, causing excessive failed logins.
Steps to Resolve the Issue
Verify Email Credentials
Ensure the correct email addresses and passwords are being used.
If unsure, reset your email password and update all devices accordingly.
Identify the Problem Device
Since multiple mailboxes may be accessed from the same device, the issue likely originates from one of these devices.
Turn off all devices accessing your email.
Turn them back on one by one and monitor when the issue recurs.
Check which device prompts the IP block and reconfigure its mail settings.
Unblock Your IP Address
If you are currently blocked, follow these steps to regain access:
Go to the IP unblock tool by logging into your cPanel account.
Follow the instructions to unblock your IP address.
Consider Using Webmail
If your email access continues to be blocked, try logging in via Webmail:
Open a browser and go to http://yourdomain.com/webmail
Enter your email credentials.
