Sending Mail With PHP3
Tim Perdue picture of Tim Perdue
Server scripting languages like Lasso and Java servlets make sending mail so complicated that you'd rather avoid it at all costs. Until recently, I have been relying on a cheap (read "free") perl script from cgi-resources.com, but I want to be able to do this from PHP.
Yesterday (1999-02-20), I decided to give email a whirl with PHP3. I needed to have a customized "thank you" page after sending the mail - like the rest of geocrawler.com and gotocity.com, the response page had to be co-brandable and customizable.
No problem for PHP. I started my research by visiting the Sample Code Archive. I wound up finding some really cool code by Jon Stevens that can take an email address and verify that it can actually receive the email. So if you want to get into some really serious form validation, you can (I didn't go that far yet, but will soon).
Jon Stevens' Code

<?php

function validateEmail ($email) {
    global $SERVER_NAME;
    $return = array (false, "");
    list ($user, $domain)  = split ("@", $email, 2);
    $arr = explode (".", $domain);
    $count = count ($arr);
    ## Here starts the modification (E.Soysal)
    if (($count>  2) and ($arr[$count - 2]=='com' or $arr[$count - 2]=='org' or
        $arr[$count - 2]=='net' or $arr[$count - 2]=='edu' or
        $arr[$count - 2]=='mil' or $arr[$count - 2]=='k12')) {
            $tld = $arr[$count - 3].".".$arr[$count - 2] . "." . $arr[$count - 1];
    } else {
    ## End of modification
        $tld = $arr[$count - 2] . "." . $arr[$count - 1];
    }
    if (checkdnsrr ($tld, "MX")) {
        if (getmxrr ($tld, $mxhosts, $weight)) {
            for ($i = 0; $i < count ($mxhosts); $i++) {
                $fp = fsockopen ($mxhosts[$i], 25);
                if ($fp) {
                    $s = 0;
                    $c = 0;
                    $out = "";
                    set_socket_blocking ($fp, false);
                    do {
                        $out = fgets ($fp, 2500);
                        if (ereg ("^220", $out)) {
                            $s = 0;
                            $out = "";
                            $c++;
                        } else if (($c > 0) && ($out == "")) {
                            break;
                        } else {
                            $s++;
                        }
                        if ($s == 9999) {
                            break;
                        }
                    } while ($out == "");
                    set_socket_blocking ($fp, true);

                    fputs ($fp, "HELO $SERVER_NAME\n");
                    $output = fgets ($fp, 2000);
                    fputs ($fp, "MAIL FROM: <info@" . $tld . ">\n");
                    $output = fgets ($fp, 2000);
                    fputs ($fp, "RCPT TO: <$email>\n");
                    $output = fgets ($fp, 2000);
                    if (ereg ("^250", $output)) {
                        $return[0] = true;
                    } else {
                        $return[0] = false;
                        $return[1] = $output;
                    }
                    fputs ($fp, "QUIT\n");
                    fclose($fp);

                    if ($return[0] == true) {
                        break;
                    }
                }
            }
        }
    }
    return $return;
}
