Attachment file not picked - File to Mail scenario

Hi,

I'm just trying out the file to mail scenario as suggested in blog:

https://www.sdn.sap.com/irj/sdn/weblogs?blog=/pub/wlg/1685 [original link is broken] [original link is broken] [original link is broken]

I created a xml file as the main mail content(main.xml). And I also have an attachment file(txt) placed at the same location. The file adapter picks the mail.xml, but not the attachment txt file. I can see the mail in my inbox, with the mail.xml added as an attachment..

I have added the "additional files" in the File adapter configuration. Also in mail adapter configuration, I have checked "Keep attachments"

Are there any other configurations I'm missing out???

When I check in XI ABAP engine, sxmb_moni, I see the following error:
