如何在UNIX计算机上为SMTP传出电子邮件设置XAMPP - How can I Setup XAMPP for SMTP outgoing Email on a UNIX machine

我用registerNewUser的方法创建了一个PHP Mail类。基本上，正如我的标题所说，该方法返回true，而它应该返回false，因为我没有收到电子邮件。有人能解释一下我做错了什么吗？(请不要评论我向用户发送未加密密码。此未加密密码是一个25个字符的字母数字随机生成的密码。安全性不是问题(我不希望使用某种类型的框架。我想手动编码，所以请不要告诉我使用PHPMailer或任何类似的东西。

编辑：我发现我需要设置XAMPP来使用SMTP发送传出电子邮件。这个问题不是重复的，因为每个其他问题的其他答案都是基于窗口的，即使这样也没有提供关于如何在XAMPP localhost服务器上设置SMTP的分步说明。

这是代码：

<?php
class Mail {
  private $headers;
  public function __construct() {
    // Setting Up Mail Headers
    $this->headers  = "MIME-Version: 1.0 'r'n";
    $this->headers .= "Content-type: text/html; charset=iso-8859-1 'r'n";
    $this->headers .= "From: Admin @ NAStepsOnline <no-reply@NAStepsOnline.com>'r'n"."X-Mailer: php";
  }
  /**
  * @desc                   Mails the User from registration email.
  *                         This function should only be called through
  *                         registerNew() within the user.class file
  * @param  str $userName   First Name of the user
  * @param  str $userEmail  Email address of the user
  * @param  str $userPass   Password of user (UNENCRYPTED)
  * @return bool            True = Mail Sent Sucessfully
  *                         False = Mail Not Sent
  */
  public function registerNewUser($userName, $userEmail, $userPass) {
    // Define Subject Line
    $subject = "Thanks " . $userName . " for Registering On NAStepsOnline.com";
    // Setting Up Message to the User
    $msg = "<html><body>";
    $msg .= $userName . " Thanks for registering at NAStepsOnline.com<br><br>";
    $msg .= "Here is your password (case sensitive): " . $userPass . "<br><br>";
    $msg .= "Please use the login form to login.<br>";
    $msg .= "To assign a sponsor to your account please visit the Profile Settings page and click on My Sponsor.<br>";
    $msg .= "If you have any problems please contact us using the Contact Us page.<br><br>";
    $msg .= "Thanks,<br>The Team @ NAStepsOnline.com";
    $msg .= "</body></html>";
    // Mailing the user Registration
    $mail = mail($userEmail, $subject, $msg, $this->headers);
    if($mail) {
      return true;
    } else {
      return false;
    }
  }
}

首先安装sendmail

sudo apt-get install sendmail

在php.ini文件中找到[mail function]并将其更改如下：

    SMTP=smtp.gmail.com
    smtp_port=587
    sendmail_from=your@gmail.com
    sendmail_path=/usr/sbin/sendmail -t -i

Windows

Now edit the `sendmail.ini`:
 [sendmail]
 smtp_server=smtp.gmail.com
 smtp_port=587
 error_logfile=error.log 
 debug_logfile=debug.log
 auth_username=username@gmail.com
 auth_password=gmail-password
 force_sender=username@gmail.com

Linux

一旦安装了sendmail，就可以运行以下命令：sudo sendmailconfig。回答所有问题的[Y]。

创建新目录：

 sudo mkdir -m 700 /etc/mail/authinfo && cd /etc/mail/authinfo

创建新文件：

 sudo touch ./gmail-auth

插入以下内容：

 AuthInfo: "U:YOUR ACCOUNT NAME" "I:YOUR GMAIL EMAIL ADDRESS" "P:YOUR GMAIL PASSWORD"

创建新的哈希图：

 makemap hash gmail-auth < gmail-auth

打开/etc/mail/sendmail.mc及以上版本，首先MAILER定义添加：

 define(`SMART_HOST',`[smtp.gmail.com]')dnl
 define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
 define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
 define(`confAUTH_OPTIONS', `A p')dnl
 TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
 define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5    LOGIN PLAIN')dnl
 FEATURE(`authinfo',`hash -o /etc/mail/authinfo/gmail-auth')dnl

重建配置并重新启动发送邮件服务

  sudo make -C /etc/mail && sudo service sendmail restart

macOS
用brew install sendmail安装自制软件和sendmail要获得安装目录，请执行以下命令：brew info sendmail。执行本答案Linux部分中相同的配置步骤。
