由于某些原因，发送到Hotmail或在Microsoft Outlook上查看的电子邮件总是显示空白，据我所知，在其他地方还好(除了使用Hotmail和Outlook的人外，没有人抱怨)。
我使用CodeIgniter，这里是电子邮件的设置:
$config['mailtype'] = "html";
$config['charset'] = "utf-8";
$config['newline'] = "rn";
$config['crlf'] = "rn";
电子邮件模板是这样的:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head><title>Welcome to <?php echo $site_name; ?>!</title></head>
<body>
<div style="max-width: 800px; margin: 0; padding: 30px 0;">
<table width="80%" border="0" cellpadding="0" cellspacing="0">

<td width="5%"></td>
<td align="left" width="95%" style="font: 13px/18px Arial, Helvetica, sans-serif;">
<img src="<?php echo base_url(); ?>/media/images/logo.png" alt="Logo" />
<br /><br />

在Outlook和Hotmail中是否缺少某些内容?谢谢!
看起来Hotmail/Outlook不喜欢换行符和crlf email配置中的"rn"。
