File to Mail Receiver with Attachment without mapping

Hi all,

I have a requirement to send forecast files to the customer as email attachment.

The file is available as plain text in an FTP source directory. XI has to pick this up and send this file as email attachment. No content in email body is required. The attachment name in the email should be the same as the filename

Everything is fine but the problem is the filename in the email is always coming as 'Untitled.xml'

Here are the my module parameters for the receiver mail adapter. I have a limitation not to use Message Mapping

Requesting expert advise if anything else is missed. Thanks in advance.

Thanks
