如何使用带有DKIM签名的Phpmailer发送电子邮件? [英] How to send email with Phpmailer with DKIM signature?

问题描述

我正在使用PHPmailer发送电子邮件.

I`m using PHPmailer to sent email.

我安装了postfix服务和DKIM-Milter来生成密钥.

I installed postfix service and DKIM-Milter to generate the key.

如果我使用命令行发送邮件，并且邮件带有显示"signed-by:mydomain.com"的DKIM签名，则效果很好

It works fine if i use command line to sent mail, and the mail is with DKIM signature displaying "signed-by:mydomain.com"

Authentication-Results: mx.google.com; spf=pass (google.com: domain of [e-mail] designates 182.50.xxx.xxx as permitted sender) smtp.mail=[e-mail]; dkim=pass header.i=@mydomain.com

DKIM-Signature: v=1; a=rsa-sha256; c=simple/simple; d=mydomain.com; s=default;
    t=1325531456; bh=+gZFhu4Id2AXb8UVbFLzDVVlChWGhvxvJUIdjdMLQsk=;
    h=To:Subject:Message-Id:Date:From;
    b=mH4GV8ayicc6UMn1uopCc9VJb5v2MiOKQpEtwJjckzoJ8ePhRKQIZI5KnzSdSoSP3

但是我想使用PHPmailer(5.1)发送支持DKIM签名的邮件，但是返回以下内容:

But i want to use PHPmailer (5.1) to sent mail with DKIM signature supported, but returns this:

Authentication-Results: mx.google.com; spf=pass (google.com: domain of [e-mail] designates 182.50.xxx.xxx as permitted sender) smtp.mail=[e-mail]; dkim=neutral (bad format) header.i=[e-mail]

DKIM-Signature: v=1; a=rsa-sha1; q=dns/txt; l=70; s=default;
    t=1325533594; c=relaxed/simple;
    h=From:To:Subject;
    d=mydomain.com; i=@mydomain.com;
    z=
    |
    |Subject:=20Testing=20email=20from=20phpmailer;
    bh=lC+16EvauA2HuJG03ArE6CtgLuY=;
    b=

我检查了class.phpmailer.php文件，它具有一些DKIM选项:

I checked the class.phpmailer.php file, and it has some DKIM options:

  public $DKIM_selector   = 'default';

  /**
   * Used with DKIM DNS Resource Record
   * optional, in format of email address '[e-mail]'
   * @var string
   */
  public $DKIM_identity   = '';

  /**
   * Used with DKIM DNS Resource Record
   * optional, in format of email address '[e-mail]'
   * @var string
   */
  public $DKIM_domain     = '';

  /**
   * Used with DKIM DNS Resource Record
   * optional, in format of email address '[e-mail]'
   * @var string
   */
  public $DKIM_private    = '';

如何配置此选项?我知道公钥和私钥，但是$ DKIM_private和$ DKIM_identity是什么?

How to configure this option? I know the public key and private key, but what`s is $DKIM_private and $DKIM_identity?

推荐答案

$ DKIM_private用于您的私钥和$ DKIM_identity，我不确定，但是它是可选的，您可以在此处找到更多信息: http://dkim.org/specs/draft- allman-dkim-base-01.html#anchor9 .这是一些示例代码.

$DKIM_private is for your private key and $DKIM_identity, well I'm not sure, but it's optional, and you can find more info here: http://dkim.org/specs/draft-allman-dkim-base-01.html#anchor9. Here is some example code.

$mail->DKIM_domain = 'mydomain.com';
$mail->DKIM_private = '/path/to/private_key';
$mail->DKIM_selector = 'default'; //this effects what you put in your DNS record
$mail->DKIM_passphrase = '1234567';
