what exactly are you checking for? An email address existing, that it validate with an @ and .xxx? A lookup on the domain name itself?

well, you can use string functions to check to see if it contains an @ and ., and that are at least 2-3 characters after the .If you want to make sure that its in particular format and not just @.xxx, then you would want to use regex. You could probably find lots of email verfication functions in that vein on google.As far as the domain name lookup, you could test that the domain exists, but not necessarily that that specific email address exists though.

So is this code no good and not work with my form if I knew were I placed it?function checkEmail($email) {if (!preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)*.([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/" , $email)) {return false;}else{$record = 'MX';list($user,$domain) = split('@',$email);if(!checkdnsrr($domain,$record)){return false;}else{return true;}}}

sorry, I didn't realize you had the actual code and were just looking to implement it into your setup......You in your code you are calling a check_email_address function. Just change/substitute the names.

For me this function works fine.

function emailCheck($m=""){	if (preg_match("/([a-zA-Z0-9_-]*)(@)([a-zA-Z0-9_-]*)(\.)[a-zA-Z0-9]{2,}/", $m))	{		return true;	}	else	{		return false;	}}

same difference, like I was saying. The names just have to match. You can put the code at the top of the page if you want.
