dkim = softfail with mail()但不是phpmailer?

我有一台运行邮件软件的服务器。该软件使用phpmailer。 如果我通过此软件发送电子邮件我没有问题,我会SPF=PASS以及DKIM=PASS

但是,当我尝试使用仅使用mail()的常规PHP文件时,我收到的邮件出现dkim=softfail (fail, body has been altered) header.i=@example.com错误。以下是具体细节。

我现在在网上查了几个小时,但我找到的只是RFC规范的链接,说这个问题是由“超过990字节的行”或“格式错误的行结尾”(两者都没有)引起的在这里申请,因为我使用chunk_split())。

在我的代码中,什么可能导致DKIM出现此问题?是否有我忽略的另一个RFC规范?

**PHP script I use:**

//build array with headers
$header = array();
$boundary = md5(uniqid(rand()));
$header[] = "MIME-Version: 1.0";
$header[] = "Content-Type: multipart/alternative; boundary = $boundary";
$header[] = "From: Me <me@example.com>";

// get html version
ob_start();
include('html.php');
$Html = ob_get_contents();
ob_end_clean();

// get TXT version
ob_start();
include('txt.php');
$Txt = ob_get_contents();
ob_end_clean();

// Build final message body
// TXT part of message
$body = "--$boundary\r\nContent-Type: text/plain; charset=UTF-8\r\nContent-Transfer-Encoding: base64\r\n";
$body .= chunk_split(base64_encode($Txt));

// HTML part of message
$body .= "--$boundary\r\nContent-Type: text/html; charset=UTF-8\r\nContent-Transfer-Encoding: base64\r\n";
$body .= chunk_split(base64_encode($Html));
$body .= "--$boundary--";

// sent email
$isMailed = mail("me@example.com","=?UTF-8?B?".base64_encode($subject)."?=",$body, implode("\n", $header));

编辑:为了帮助解决这个问题,以下是我使用上述脚本获得的示例电子邮件标题:

1 个答案:

答案 0 :(得分:0)

你的服务器是什么?你使用什么类型的邮件服务器?

任何仍在运行dkim-milter的人都可以交换到OpenDKIM 在几分钟内 - 保持现有密钥,DNS设置, 等

如果您正在运行CentOS 6,例如,如果您启用了EPEL 可以"yum install opendkim",它将安装最新的 使用最常见的默认版本发布OpenDKIM版本 配置,包括服务器的一组默认密钥。该 opendkim软件包可以在Fedora 14-17和的稳定回购中找到 EL 5-6。

第二种排除方法:  如果您正在使用\ n作为换行符(标题行的示例结尾)。但你必须使用\ r \ n。这为我解决了!
