Question

Kayako帮助台在尝试以名称或主题发送外国字符时总是出错，它来自swiftmailer。我决定更新swiftmailer，看看是否会修复。事情正在发挥作用（我需要做一些重命名，因为他们使用SwiftMailer_而不是Swift_所以重命名swiftmailer部分使用SwiftMailer而不是Swift，因为他们已经有了Swift类）。无论如何，当事情正在发挥作用时，问题是当附件以编码方式发送时发送的电子邮件，而outlook 2010无法看到附件中的所有原始base64编码。为什么这样做（我需要改变什么？）？谢谢！！这是我的示例消息（已修改为更改域名等）：

Answer 1

所以看一下标题，我认为它必须与boundary=行中的所有废话有关，所以swiftmailer/classes/Swift/Mime/SimpleMimeEntity.php我改变了：

$this->_boundary = '_=_swiftmailer_v4_'.time().'_'.md5(getmypid().mt_rand().uniqid('', true)).'_=_';

到

$this->_boundary = 'swiftmailerv4'.time().'x'.md5(getmypid().mt_rand().uniqid('', true));

现在事情正在发挥作用。

但是，由于它似乎搞乱了电子邮件客户端不支持的标题字段，我想知道如果主题或来自/来自/ cc需要字符，我是否会遇到任何问题编码？我无法使用swiftmailer的V6，因为kayako不支持php7。

将swiftmailer从4.1.3更新到5.4.9会导致附件被编码在正文中
