(Deprecated) Disable SNI mail services for domains

This function is deprecated and always fails.

Note:

Mail SNI is always enabled. cPanel & WHM no longer allows mail SNI to be disabled.

  • Functions that disable Mail SNI fail and make no changes.
  • Functions that enable Mail SNI succeed with a warning that Mail SNI is always enabled.
get/disable_mail_sni

Query parameters

domainstring
Example:example.com

The account's domain. You may pass multiple domains using additional numbered parameters (e.g., domain-1, domain-2).

Note: This parameter has no effect — this function always fails regardless of any input because mail SNI can no longer be disabled.
