还可以查看PEAR邮件包PEAR mail Page

它似乎比内置的标准mail()函数健壮一些(如果标准函数不够的话)。

下面是该页面的一段摘录，展示如何使用它。PEAR邮件发送()用法

<?php
    include('Mail.php');

    $recipients = 'joe@example.com';

    $headers['From']    = 'richard@example.com';
    $headers['To']      = 'joe@example.com';
    $headers['Subject'] = 'Test message';

    $body = 'Test message';

    $smtpinfo["host"] = "smtp.server.com";
    $smtpinfo["port"] = "25";
    $smtpinfo["auth"] = true;
    $smtpinfo["username"] = "smtp_user";
    $smtpinfo["password"] = "smtp_password";


    // Create the mail object using the Mail::factory method
    $mail_object =& Mail::factory("smtp", $smtpinfo); 

    $mail_object->send($recipients, $headers, $body);
?> 

你也可以在https://github.com/PHPMailer/PHPMailer上使用PHPMailer类。

它允许您使用邮件功能或透明地使用smtp服务器。它还可以处理基于HTML的电子邮件和附件，因此您不必编写自己的实现。

这个类是稳定的，它被许多其他项目使用，如Drupal、SugarCRM、Yii和Joomla!

下面是上面页面的一个例子:

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'user@example.com';                 // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also accepted

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('joe@example.net', 'Joe User');     // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional
$mail->addReplyTo('info@example.com', 'Information');
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');

$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

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

原生PHP函数mail()不适合我。它发出消息:

此邮件服务器在试图发送时需要身份验证 到非本地电子邮件地址

所以，我通常使用PHPMailer包

我已经从GitHub下载了5.2.23版本。

我只选择了2个文件，并将它们放在我的源代码PHP根目录中

class.phpmailer.php class.smtp.php

在PHP中，需要添加该文件

require_once('class.smtp.php');
require_once('class.phpmailer.php');

在此之后，它只是代码:

require_once('class.smtp.php');
require_once('class.phpmailer.php');
... 
//----------------------------------------------
// Send an e-mail. Returns true if successful 
//
//   $to - destination
//   $nameto - destination name
//   $subject - e-mail subject
//   $message - HTML e-mail body
//   altmess - text alternative for HTML.
//----------------------------------------------
function sendmail($to,$nameto,$subject,$message,$altmess)  {

  $from  = "yourcontact@yourdomain.com";
  $namefrom = "yourname";
  $mail = new PHPMailer();  
  $mail->CharSet = 'UTF-8';
  $mail->isSMTP();   // by SMTP
  $mail->SMTPAuth   = true;   // user and password
  $mail->Host       = "localhost";
  $mail->Port       = 25;
  $mail->Username   = $from;  
  $mail->Password   = "yourpassword";
  $mail->SMTPSecure = "";    // options: 'ssl', 'tls' , ''  
  $mail->setFrom($from,$namefrom);   // From (origin)
  $mail->addCC($from,$namefrom);      // There is also addBCC
  $mail->Subject  = $subject;
  $mail->AltBody  = $altmess;
  $mail->Body = $message;
  $mail->isHTML();   // Set HTML type
//$mail->addAttachment("attachment");  
  $mail->addAddress($to, $nameto);
  return $mail->send();
}

这招很管用

你可以做一个测试，如果你需要它通过修补如下代码

# SSH into droplet
# go to project
$ php artisan tinker
$ Mail::send('errors.401', [], function ($message) { $message->to('emmanuelbarturen@gmail.com')->subject('this works!'); });
# check your mailbox

试试这个:

<?php
$to = "somebody@example.com";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: webmaster@example.com" . "\r\n" .
"CC: somebodyelse@example.com";

mail($to,$subject,$txt,$headers);
?>
