我正在运行一个脚本来登录到 IMAP/POP 邮箱，将内容转发到新的电子邮件地址，然后从邮箱中删除它们。
它现在几乎可以工作了，除了出于某种奇怪的、莫名其妙的原因，发送到我们 Ning 网站的转发附件图像看起来被压扁了，而带有图像附件的电子邮件直接发送到 Ning 的上传电子邮件地址，看起来格式完美。因此，我们转发的电子邮件格式有所不同。好像附件中的图像与原始图像不完全相同。
被挤压的图片上传 http://members.bigmanwalking.com/photo/a-test-photo?context=latest 示例
任何帮助都会很棒...这是一个谜，为什么图像应该通过这个脚本突然失去形状。

找到了答案。这是为了检测附件的 Mime 类型，并将 Mime 类型添加到传出电子邮件中的附件中。完成此操作后，照片以正确的比例出现在Ning上。
