Import email fails

Hi there,

the attached .eml is part of a zip email export from a zoho account.
I now want to import these zips into another zoho account.
At the end of the importing process, the message "import successfully completed" appears, but the folder into which the emails are supposed to be imported is still empty.
Same thing happens when I unzip the exported emails and import an individual .eml file. The message says "import successful", but there is no imported message.
However the .eml files definitely contain emails.

(I had to change the extension so I could attach the .eml file)

Thank you for your help
Thomas
