Please note the following: 

  • Upload via email only works for file attachments, the body of the email will not be uploaded to Box.
  • The cumulative size of the attachments cannot exceed 80MB.
  • The folder owner and sender will receive a notification that files were uploaded successfully.
  • Collaborators will also receive a notification if upload notifications are enabled for the folder.

 

Security for Upload by Email:

 
Box's mail servers accept TLS encryption for email uploads. Box's Incoming mail servers used for the "Upload by Email" feature support opportunistic TLS. This means that when a customer's mail server connects to Box to relay an email, Box's mail servers will advertise that TLS encryption is available and the customers' mail server can choose to use it. If a customer's mail server is configured to use TLS encryption, all email uploads will be encrypted in transit.
 
Another way to look at this is that once a file enters Box's system, it will be uploaded via TLS using our API. If you want the email itself (for "Upload by Email") to be encrypted, the customer will need to put an email rule in place that ensures all email traffic to box.com is sent via TLS. Note: If an email originates from outside of Box (other 3rd party email clients), Box is unable to provide encryption prior to the content entering Box.

 

Troubleshooting Unsuccessful Uploads

 

Add a mention to this new section that if a user runs into the issue with Date strings containing slashes.  i.e. 2/19/17 in a filename will usually get converted to 2_19_17 or 2:19:17. Make sure the mail server is doing the replacement.
