We have a new documentation site for cPanel & WHM! You can find our new documentation site at docs.cpanel.net.
We will continue to maintain our API documentation on this server.
Use this feature to set the mailbox quota, or manage disk usage.
The quota for an email account defines the amount of mail that the account can store. When the account exceeds this limit, the system returns any incoming mail to the sender with a message that states that the recipient’s mailbox is full. The system administrator can change this behavior in WHM's Exim Configuration Manager interface (WHM >> Home >> Service Configuration >> Exim Configuration Manager).
To change a mail quota, perform the following steps:
Select the Unlimited or Maximum. For a custom quota, enter a new amount in the Mailbox Quota text box and select a file size from the menu.
Delete old or large messages from your mailbox to recover disk space. The Email Disk Usage interface (cPanel >> Home >> Email >> Email Disk Usage) will appear.
Use this feature to allow or suspend a user's ability to log in, receive mail, or send remote mail.
To allow or suspend specific abilities for a user, perform the following steps:
When you suspend an email account, the system will still send and receive local mail.
When you suspend an email account, the system also suspends any aliases or forwarders that redirect email to the account.
Use this feature to create or change the password for an account. Enter and confirm the new password in the appropriate text boxes.
Use a secure password. A secure password does not contain a dictionary word, and it does contains uppercase and lowercase letters, numbers, and symbols.
0indicates a weak password, while
100indicates a very secure password.
Allow users to access cPanel with external authentication credentials. The Password and Security interface (cPanel >> Home >> Preferences >> Password & Security) will appear.
This feature attempts to automatically configure your email client to access your cPanel email addresses. An email client allows you to access your email account from an application on your computer or mobile device (for example, Apple® Mail).
To access this feature, click Set Up Mail Client in the Email Accounts tab. A new interface will appear.
To configure your mail client, perform the following steps:
Select and download the appropriate configuration file from the list.
We strongly recommend that you use SSL/TLS.
When the configuration process finishes, your email client will automatically open and log in to your email account.
You may need to manually configure your mail client. Enter
mail.domain.com for the name of the server, where
domain.com represents your domain.
Only use the
To send a mail account's client configuration instructions to a different email address, enter the address in the Email Instructions text box and then click Send.
Use this feature to access your calendars and contacts on your personal devices. A new interface will appear.
This option only appears if your hosting provider enables the Calendars and Contacts feature for your account.
Use this interface to access your default email address. The system creates this unique email account when your hosting provider creates your cPanel account. The account's username and password are identical to your cPanel account name and password.
The system uses
firstname.lastname@example.org as the default account, where
account represents your cPanel account username and
domain.com represents your main domain. You cannot rename, delete, or place a quota on the default account. We recommend that you create a separate email account for daily use.
The system also uses this address as the default From and Reply-to address on outgoing email that your account's PHP scripts send.
Because of the way the maildir mailbox format calculates disk usage, a discrepancy between reported and actual disk usage may exist for the default email account. For more information about mailbox formats, read our Mailbox Conversion documentation.
Use this interface to enable or disable the shared address book. A shared address book allows you to include a system-managed address book that serves as a user directory and allows for collaboration. You can import or export the contact list and transfer it to other email clients.
Set the appropriate toggle to enable or disable user directory collaboration.
You can access the shared address book in the Horde webmail Shared Address Book interface.
Roundcube webmail does not include a shared address book.
This option defaults to On.
