My site registration requires the user not to type their own password instead system generates it for them and send the password to the registered email. This feature is a good way to slow the multi-accounts problem in community site. But their are email services that was so eary to sign up with like yuurok and sometimes user user fast.ph or mail2.ph email add like in this way 6390918646464@fast.ph then after the registration the password will be sent to their mobile phone lol, coz fast.ph and mail2,ph is a mailtosms service. Thats why i will stick my registration to yahoo and gmail only or a code which i can block several email domains that i want to block.

Thinking about it you may want to use an array rather than hard code lots of emails into your code eg:

$email = "foobar@ymail.con";
$list = array("gmail","google","yahoo","ymail");
$email = explode("@",$email);
$email = str_replace($list,"@",$email[1]);
if(substr_count($email,"@")>0){
//ok
}else{
//not ok
}
