in tab dns-manager of ispconfig2 I have added 7 MX record of google. but when I check with http://www.checkdns.net it has shown: Domain examble.com.vn has no MX records, but it has A record for domain. This configuration is not recommended so I can't use google apps mail. this main problem is it can't see any MX record although i have added. pls help me to solve this.
