weird looking logic in ms-edit.php vs ms-functions.php

[Denis-de-Bernardy]

In ms-edit.php, you can only update the site admin's email if it's a valid email:

		if( is_email( $_POST['admin_email'] ) )
			update_site_option( "admin_email", $_POST['admin_email'] );

But in ms-functions.php, there is a check in newblog_notify_siteadmin(), that goes:

	$email = get_site_option( 'admin_email' );
	if( is_email($email) == false )
		return false;

which seems to indicate that a MU install can live without a site admin email. so, question... is it possible, or not?

The MU installer was not added to trunk but did require a valid email address.

The first check is to ensure that when the MU site options were saved that the email provided for the site admin (now super admin) was valid.

The admin_email address record can be edited or removed directly from the database. The second check is to ensure that what was retrieved from the site options was a valid email address.

Seems invalid then.
