We have Zimbra 8.0.3 OS edition server. Our server has several A-entries in DNS-server. Let's suppose they are aaa.mydomain.com, bbb.mydomain.com and ccc.mydomain.com. Could anybody say what I should do to redirect users to page 404 when they use bbb.mydomain.com, ccc.mydomain.com and server IP-address but give them access to mail web-client if they use aaa.mydomain.com?
Thanks in advance.
