here is the validation code

function check_email_address($email)

{

// First, we check that there's one @ symbol, and that the lengths are right

if (!ereg("^[^@]{1,64}@[^@]{1,255}$", $email))

{

// Email invalid because wrong number of characters in one section, or wrong number of @ symbols. return false;

}

// Split it into sections to make life easier

$email_array = explode("@", $email); $local_array = explode(".", $email_array[0]);

for ($i = 0; $i < sizeof($local_array); $i++)

{

if (!ereg("^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$", $local_array[$i])) { return false;

}

if (!ereg("^\[?[0-9\.]+\]?$", $email_array[1])) {

// Check if domain is IP. If not, it should be valid domain name

$domain_array = explode(".", $email_array[1]);

if (sizeof($domain_array) < 2)

{

return false;

// Not enough parts to domain }

for ($i = 0; $i < sizeof($domain_array); $i++)

{

if (!ereg("^(([A-Za-z0-9][A-Za-z0-9-]{0,61}[A-Za-z0-9])|([A-Za-z0-9]+))$", $domain_array[$i]))
