我正在开发一个解析电子邮件收件箱的脚本。如何判断消息部分是附件还是嵌入式图像？这个示例邮件是从一个用户发送的，该用户告诉我他的客户嵌入了图像，但是disposition =“Attachment”看起来像一个附加的图像，我看到AppleMail使用“内联”似乎更合理......
我还检查了msg文本以查看它是否引用了附加文件，但在此示例中也没有对文件的引用 - 但用户坚持说它们是嵌入的，而不是附加的。
消息的结构：

检查图像是否由[ifid]内联的最佳方法。我检查过各种邮件申请。它们以不同方式处理内联附件。 Zoho邮件标志着
[disposition] =＆gt;内联
实时邮件标记
[disposition] =＆gt;附件
他们都设置了
[ifid] =＆gt; 1 [id] =＆gt; ＆LT; 0.28876465441.6812139177583476518.150d8a30c19__inline__img__src＆GT;
如果[ifid] => 1那么它是内联图像，[id]将是图像cid。下载内联附件并替换
SRC = “CID：0.28876465441.6812139177583476518.150d8a30c19__inline__img__src”
使用下载的路径

嵌入式图像将是“multipart / related”类型的MIME主体部分的第二个及后续子元素。附加的图像将是“multipart / mixed”类型的MIME主体部分的子项。
