Fetch only a single set of Email Address

Yes, site administrators can manage all email addresses on the subsite domain (as defined as home_url seen on /wp-admin/network/sites.php), but not the ones belonging to other domains found in cPanel. Is this not working for you?

Other users can manage their own (by user_email) if, and only if, they, or their role, has granted a custom capabilty “cpanel” (and their registered user_email is on site domain).

By “a particular set” do you mean limiting to certain email addresses, not all on domain, for Administrators?

In that case such set has to be defined somewhere, and I may add a filter, passing back the site, in a soon upcoming development version, for you to test. Assuming you are able to add filters in another plugin or functions.php.

Please update to and test version 2.6.2-beta from development version

Then add something like this in a plugin or functions.php:

add_filter( 'wf_cpanel_email_site_admin_emails', function( array $allowed_emails, \WP_Site $site ) {
	if ( $site->domain === 'domainb.com' ) {
		$allowed_emails[] = '[email protected]';
		$allowed_emails[] = '[email protected]';
		$allowed_emails[] = '*@domainb.com';  // for default
	}
	return $allowed_emails;
}, 10, 2 );

I just place the code with the development version yet I can still see other domain emails

It works here, so you must debug.

Verify version 2.6.2-beta
Verify being a site administrator user, not a Super Admin user
Verify looking at page wp-admin/admin.php?page=wf-cpanel-email-accounts

echo or var_dump some info inside your filter function, like $site->domain and return array $allowed_emails not being empty.

After some misunderstandings, I got it right, as this about single site installations (not a multisite, as I assumed).

Please upgrade to version 2.7 or later and add this to you wp-config.php:
define( 'WF_CPANEL_EMAIL_SITE_DOMAIN_ONLY', true );

Thanks for suggesting this, and many thanks for your patience. I close this as resolved. If any issues, please open a new thread.

As said.
