# Enable SNI mail services for domain

This function enables SNI mail services on the specified domains.

Warning:

Mail SNI is always enabled.
* Mail SNI is not compatible with Webmail and will not function for any Webmail connection. Webmail connections use the cPanel service SSL certificate.
* Functions that enable Mail SNI succeed with a warning that Mail SNI is always enabled.
* Functions that disable Mail SNI fail and make no changes.

Important:

  When you disable the Calendars and Contacts, Mail Receive, Web Disk, Webmail, and Web Server roles, the system disables this function.
