I dont have a solution sorry... but put your email input type as email.

<input type="email" name="emailmalling" id="emailmalling"/>

<input type="email" name="emailmalling" id="emailmalling"/>

Sorry I don't have a solution atm, will look at it later, however do not change your text input to email like suggested above, this is html5, and this input type is not supported by IE or Safari.

check this code for email validtion. it works.

function valid_domain_part($domain_part) { 
            if(preg_match("/[^a-zA-Z0-9@#\[\].]/", $domain_part)) { 
                return false; 
            } 
            elseif(preg_match("/[@]/", $domain_part) && preg_match("/[#]/", $domain_part)) { 
                return false; 
            } 
            elseif(preg_match("/[\[]/", $domain_part) || preg_match("/[\]]/", $domain_part)) { 
                $dot_pos = strrpos($domain_part, "."); 
                if(($dot_pos < strrpos($domain_part, "]")) || (strrpos($domain_part, "]") < strrpos($domain_part, "["))) { 
                    return true; 
                } 
                elseif(preg_match("/[^0-9.]/", $domain_part)) { 
                    return false; 
                } 
                else { 
                    return false; 
                } 
            } 
            else { 
                return true; 
            } 
        } 
        // trim() the entered E-Mail 
        $str_trimmed = trim($temp_email); 
        // find the @ position 
        $at_pos = strrpos($str_trimmed, "@"); 
        // find the . position 
        $dot_pos = strrpos($str_trimmed, "."); 
        // this will cut the local part and return it in $local_part 
        $local_part = substr($str_trimmed, 0, $at_pos); 
        // this will cut the domain part and return it in $domain_part 
        $domain_part = substr($str_trimmed, $at_pos); 
        if(!isset($str_trimmed) || is_null($str_trimmed) || empty($str_trimmed) || $str_trimmed == "") { 
          echo  "You must insert something"; 
            return false; 
        } 
        elseif(!valid_local_part($local_part)) { 
            $this->email_status = "Invalid E-Mail Address"; 
            return false; 
        } 
        elseif(!valid_domain_part($domain_part)) { 
            $this->email_status = "Invalid E-Mail Address"; 
            return false; 
        } 
        elseif($at_pos > $dot_pos) { 
            echo "Invalid E-Mail Address"; 
            return false; 
        } 
        elseif(!valid_local_part($local_part)) { 
            echo "Invalid E-Mail Address"; 
            return false; 
        } 
           
		      elseif(($str_trimmed[$at_pos + 1]) == ".")
			   { 
            echo "Invalid E-Mail Address"; 
          
        } 
        elseif(!preg_match("/[(@)]/", $str_trimmed) || !preg_match("/[(.)]/", $str_trimmed)) { 
            echo "Invalid E-Mail Address"; 
         
        } 
        else { 
            
        } 

}

sorry i missed the starting code. this is the full function code of email validation

function email_valid($temp_email) { 
######## Three functions to HELP ######## 
        function valid_dot_pos($email) {

                    return false;
