I am trying to use the SMTP functions within Python to send a file to a Box folder. This works when I use Outlook or AT&T web mail (both sending to my own Box account and the one I need to send to at another University), so I know I am authorized. When I use my app to send a file to my own email address, it works; the file appears in my in-box and is correct. When I try to send using my Python code, I get:
| Your attempt to email file(s) into 'a folder' was not successful. This could be due to the following reasons: |
| - Your collaboration privilege did not allow you to upload into the folder (I have checked this - I have the privilege and it works using an email client) |
| - A file of the same name already exists and the folder owner disabled file-overwriting for this folder (I have checked this, there is no such existing file). |
| - The file you attached exceeded file size limit (It is a small file, a few kB). |
| - The owner of this folder does not have sufficient space in their account (my University account has unlimited storage). |
- You did not attach a file (yes, it is there; when I change nothing but the destination email and send it to my own account, the file goes through and is correct).  Is this related to the MIMEType or something like that? I would rather not use the Box API if I can avoid it, because this should be dirt-simple. What is the email handler in the Box system looking for that I am not providing?
