2. Locate the Proxy subdomains setting and select On.

Additional settings

You can find the following additional AutoConfig and Autodiscover settings in the  Domains  section of WHM’s  Tweak Settings  interface (Home >> Server Configuration >> Tweak Settings):

Preferred mail service to configure to use for Thunderbird and Outlook® autodiscover and autoconfig support

This setting allows you to choose the email transfer method to use with Thunderbird and Outlook with Autodiscover and AutoConfig support.

This setting defaults to imap.

Notes:

• We recommend that you select IMAP and not POP3.
• You must enable the Thunderbird and Outlook autodiscover and autoconfig support (enables proxy subdomain and SRV record creation) option in order to configure this setting.

Host to publish in the SRV records for Outlook autodiscover support

Microsoft Outlook®’s Autodiscover service searches DNS for an SRV record for an email inbox’s domain that points to a particular server for Autodiscover. By default, this server is cpanelemaildiscovery.cpanel.net.

This setting allows system administrators to perform the following actions:

• Choose the host that the system publishes to the SRV records.
• Change the default host if they have an SSL-enabled host with an SSL certificate that a Certificate Authority signs.
• Use their own server for Outlook® Autodiscover. Enter that server’s Fully Qualified Domain Name (FQDN) in the available text box.
• When you enable the Host to publish in the SRV records for Outlook autodiscover support feature, the system queries the server that you specify for the Autodiscover settings. You must have a custom XML file for this feature to function properly.

Notes:

• For more information about how to use a custom XML file, visit Mozilla’s autoconfiguration page, or the Exchange’s Autodiscover page.
• You must enable the Thunderbird and Outlook autodiscover and autoconfig support (enables proxy subdomain and SRV record creation) option in order to configure this option.

For more information about Microsoft Outlook’s Autodiscover feature, visit Microsoft’s Support website.

Warning

We recommend that you use signed certificates that a Certificate Authority (CA) signed, rather than self-signed certificates, which may cause security issues. If you use a self-signed certificate, the browser may generate a warning message.

Use AutoConfig and Autodiscover

To use AutoConfig and Autodiscover, enter a cPanel email address and password in your mail client. The services will automatically configure your mail client.
