我想通过 telnet 发送一封带有 PHP 的电子邮件,但这里出了点问题。
$telnet = array();
$telnet[0] = "telnet 10.0.50.6 25\r\n";
$telnet[1] = "HELO osiris.com\r\n";
$telnet[2] = "MAIL FROM:$replyTo\r\n";
$telnet[3] = "RCPT TO:$emailsTo\r\n";
$telnet[4] = "DATA\r\n";
$telnet[5] = "From:$headers<$replyTo> \r\n To:$emailsTo\r\n Subject:$emailSubject\r\n $body\r\n\r\n .\r\n";
@$fp = fsockopen('10.0.50.6', 25);
$count=0;
if (!$fp){
echo 'connection fail';
return false;
}else{
foreach ($telnet as $current) {
fwrite($fp, $current);
$smtpOutput=fgets($fp);
$g=substr($smtpOutput, 0, 3);
if (!(($g == "220") || ($g == "250") || ($g == "354")|| ($g == "500"))) {
echo 'connection 2 fail';
return false;
}else{
$count=$count+1;
echo $count.'<br>';
if ($count>5){
fclose($fp);
return true;
}
}
结果是:
telnet 10.0.50.6 25
