如何在biztalk中设置POP3接收位置，重新使用用于文件接收位置的相同编排和管道？

Question

我想发送带有csv附件的电子邮件，并通过POP3选择它们，映射并通过biztalk放入SQL数据库。

我有一个文件接收位置，可以选择一个文件。

接收位置属性：

管道配置

我将文件粘贴到文件夹中。

该文件由biztalk选取。

显示正在处理的文件的日志：

数据在映射后插入数据库中。

我创建了一个类似于文件接收位置的电子邮件位置。

邮件属性。

POP3属性。

管道配置。

我通过邮件测试相同的csv文件。

收到附件的邮件。

邮件由biztalk处理和删除。

我得到的错误。

Edit1：我通过停止编排拦截了通过POP3获得的biztalk中的消息，并将其与通过文件位置获得的消息进行了比较。

电子邮件：

档案信息：

电子邮件有一个额外的正文部分，是否可以使用mime解码器直接在接收位置忽略它？否则我有什么选择？如果可能，我希望避免编辑业务流程或添加新的业务流程。
