I have a WPMU site with the registration turned off.
Also i have a google.apps mail account, with the mail.mydomain.com subdomain set up via CNAME in DNS settings.
All works fine for me, and i can open my mail.mydomain.com address reaching my mail ok? but some of my users cant - it opens WPMU page for them (http://mydomain.com/wp-signup.php?new=mail.mydomain.com). Why is that so, and how can i fix it?
Thanx in advance.
