Non-Webmail Access Control

Disabling Non-Webmail access restricts the access to the mailbox by scripts and mail clients (like MS Outlook, Thunderbird, Apple Mail) using the IMAP, POP3, and SMTP protocols. With Non-Webmail access disabled, connections to the mailbox over IMAP/POP3/SMTP are not allowed, and you would only be able to access the account via Webmail Classic and Roundcube. When combined with two-factor authentication, this can make your mail account even more secure.

The Non-Webmail access can be controlled per mailbox via the Webmail Classic, and Roundcube interfaces. Here is how you can do it step-by-step:

• Roundcube
• Webmail Classic

Roundcube

The Non-Webmail access can be disabled via the Roundcube Webmail > Settings menu > Non-Webmail Access > press the Disable button next to "Non-Webmail access is enabled". 

To enable it again, go to the same menu and press the “Enable” button next to "Non-Webmail access is disabled".

Webmail Classic

The Non-Webmail access can be disabled via the Classic Webmail > Options menu > Password & Security > press the Disable button next to "Non-Webmail access is enabled". 

To enable it again, go to the same menu and press the “Enable” button next to "Non-Webmail access is disabled".

Control Panel

The Non-Webmail access can also be disabled and enabled via the Control Panel. Detailed instructions on how to do so, are available in the Security - Non-Webmail Access Restriction article.
