ClearOS provides both POP and IMAP servers for providing mail delivery to desktop clients.
If you did not select this module to be included during the installation process, you must first install the module.
You can find this feature in the menu system at the following location:
The base mail domain is used by a number of apps: SMTP Server, IMAP, Mail Filter, etc. Each app saves this information in its own configuration file, but we really only want to see the domain in one place in the user interface. That's where the Mail Settings app comes in.
The mail server supports four different protocols:
We strongly suggest using the secure protocols if possible. Keep in mind, you will need to generate an SSL Certificate to enable the secure protocol.
Some mail clients support the push e-mail feature (also known as the IMAP Idle feature). With this feature enabled on both the server and client, e-mail will appear in your mailbox as soon as it arrives. This feature is most useful on wireless and handheld devices. The following mail clients are known to support push e-mail (IMAP Idle):
If you are using Mozilla's Thunderbird, click on <navigation>Tools|Account Settings</navigation>, then select “Server Settings” from the navigation bar. Ensure the Use secure connection (SSL) checkbox is enabled.
Next, click on the “Advanced” tab, and ensure the “This server requires a secure connection (SSL)” checkbox is enabled.
For other mail clients, similar set-up/configuration will exist. Please refer to documentation for your mail client for specific instructions.
