【问题描述】：

I can not send mail using the PHPMailer lib. My site is hosted on dreamhost,

使用 SMTP gmail，我可以更正确地发送到主机提供的配置，唯一的回报是： SMTP 错误：无法连接到服务器：php_network_getaddresses：getaddrinfo 失败：名称或服务未知（0） SMTP 连接（）失败。我的代码：

<?php

date_default_timezone_set('Etc/UTC');

require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php';

$mail = new PHPMailer;

$name       = trim(stripslashes($_POST['name']));   
$from       = trim(stripslashes($_POST['email']));
$subject    = trim(stripslashes($_POST['subject']));
$message    = trim(stripslashes($_POST['message']));

$mail->isSMTP();
$mail->SMTPDebug = 2;
$mail->Host = 'mail.example.com.br';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'e-mail@example.com';
$mail->Password = 'password';
$mail->SMTPSecure = 'tls';
$mail->Debugoutput = 'html';

$mail->isHTML(true);
$mail->setFrom($from, $name);
$mail->addReplyTo($from, $name);
$mail->addAddress('email@example.com');
$mail->Subject = $subject;
$mail->Body = $message;

 if(!$mail->send()) {
   echo 'Message could not be sent.';
   echo 'Mailer Error: ' . $mail->ErrorInfo;  
  } else {
   echo 'Message has been sent';
}

【解决方案1】：

我设法解决了这个问题，先把发给自己客户端的邮件替换为sender@example.com，然后尝试了dreamhost的一些文档，做了必要的修改，代码：

  date_default_timezone_set('Etc/UTC');

  require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php';

  $subject    = trim(stripslashes($_POST['subject']));
  $name       = trim(stripslashes($_POST['name']));
  $from       = trim(stripslashes($_POST['email']));
  $body       = trim(stripslashes($_POST['message']));

  $mail = new PHPMailer;

  $mail->isSMTP();
  $mail->CharSet = 'UTF-8';
  $mail->SMTPDebug = 1;
  $mail->Host = 'mail.example.com.br';
  $mail->Port = 587;
  $mail->SMTPAuth = true;
  $mail->Username = 'sender@example.com.br';
  $mail->Password = 'password';
  $mail->Debugoutput = 'html';

  $mail->isHTML(true);
  $mail->setFrom('sender@dexample.com.br', 'DontAnswer');
  $mail->addReplyTo($from, $name);
  $mail->addAddress('contact@example.com.br');
  $mail->Subject = $subject;
  $mail->Body = $body;

  if(!$mail->send()) {
      echo 'Message could not be sent.';
      echo 'Mailer Error: ' . $mail->ErrorInfo;
  } else {
      echo 'Message has been sent';
  }

在dreamhost 文档中说应该在setFrom() 方法中重复发送电子邮件；经过这些更改后，表单完美运行。
