Overview

Service proxying configures local services to proxy requests for a cPanel account’s domains to a remote server. You can manage a cPanel account’s service proxying via API with the WHM API 1 set_service_proxy_backends and unset_all_service_proxy_backends functions.

You can configure the following services via service proxying:

• Web Server (httpd)
• Mailbox (Dovecot®)

For information about a specific service, read our cPanel service daemons documentation.

Service proxy configuration

All service proxy configurations assign a host as the general proxy backend server. In the absence of any other configurations, all compatible services proxy requests to that proxy backend server.

You can also configure different services to use different proxy backend servers. For example, you can configure the web server (httpd) to proxy requests to web.example.com server, while Dovecot proxies its requests to the mail.example.com server.

To create such a configuration, you must first assign a general proxy backend server. Then, assign other backend servers to the related service group. For example, you can assign the web.example.com server as the general proxy backend server. You can then assign the mail.example.com server as the Mail service group’s proxy backend server.

Service proxy groups

Service proxy groups consist of a group of one or more related services:

Mail

The Mail service group consists of the Dovecot service, which handles the IMAP and POP3 protocols.

Unsuspend an account

To remove service proxying, unsuspend the account. For example, the Live Transfer feature proxies services to the destination server. The feature then suspends the account. You can unsuspend the account on the source server to disable proxying.
