Php 带有SMTP的Codeigniter电子邮件显示奇怪的格式

我有一个HTML消息如下

<p>This is a bank account number *********0205</p>
<p><b>This is a test email.</b></p>
<p>This is my email me@me.com</p>
<p>This is a link <a href='https://xxxxxx.uslogistics.com/images/logo_big.png'>https://xxxxxx.uslogistics.com/images/logo_big.png</a><p>

这是一个银行账号************0205

这是一封测试邮件

这是我的电子邮件me@me.com

这是一个链接

我想通过SMTP发送该邮件。使用的主机是smtp.office365.com

我使用的是Codeignitor，当我在没有SMTP的情况下发送电子邮件时，收到的电子邮件显示良好，请参见下面的（图像和代码）

您是否尝试过在PHP var中保存您的正文，然后将其分配到CI或PHPMailer中的
$mail->body
中？如果您是指在PHPMailer中，我刚刚执行了此操作，但它仍能正确显示电子邮件。看起来像是CI的邮件程序中的错误。那些
=
字符表示它使用的是引用的可打印传输编码，但是如果它弄乱了编码的其他方面，它可能会留下这样的工件。您是否使用最新的CI？是最新版本3.1.7
