$it=split("@",strtolower($email));
//Check if a user is using fake email and this email in our array
 if(in_array($it[1],$restricted_domains)){
    exit('&result=email_not_allow&load=ok');
} 
Add this line into your language file e.g languages/en.xml to show different error message 
  <email_not_allow>This email address is not allowed ! </email_not_allow> 

If  you want to allow only specific doamin you can use this syntax

 //Allow domain array . to add more user comma in $allow_domain string
$allow_domains=array("gmail.com","yahoo.com","hotmail.net","aol.com","ymail.com");
$it=split("@",strtolower($email));
//Check doamin
if(!in_array($it[1],$allow_domains)){
exit('&result=email_not_allow&load=ok');
}
 
Add this line into your language file e.g languages/en.xml to show different error message 
  <email_not_allow>This email address is not allowed ! </email_not_allow>
