Auditing

For uploads via web to Inbox, you can audit the upload details in the folder history by filtering the logs based on Folder path and selecting the interface as web. For uploads via email, select the interface as Email.

We also provide full audit logs for inbound emails. This is useful for accessing additional information such as the sender's email address, sender's name, attachment details, email body, etc.

Troubleshooting

Inbound Email Logs can be used to help you troubleshoot failures in uploads via email. If you see the status as Skipped or Failure, the details column in these logs provides additional insights into why there is an issue with the corresponding inbound email.

There are several reasons why email to inbox may result in a failure.

"Sender <email address> is not allowed to upload to this folder" - This error message results from the setting Whitelisting email domains turned on, this will result in an error if the sender's domain or email address is not in the whitelisted email domains.

"Email Authentication Failed" - This message is primarily because of a verification step in Files.com. This verification step is to validate the use of SPF, DKIM, and DMARC and their signatures on the message, it is primarily used to prevent spoofing, spamming or other misuse. This check is controlled by the setting called Enable inbound email authentication under Sharing -> Sharing Settings. When enabled, emails that do not pass the authentication checks will be discarded by our system and logged as a failure. In such cases, contact the sender and check whether their mail server or an intermediary server is causing this failure.

Size Limit For Messages

Inboxes can accept email messages up to 40MB in size. The limit applies to the total size of the email, including any attachments or embedded images.

If a larger email than 40MB is sent to your inbox, the email sender will receive a message "Your message is larger than the size limit for messages. Please make it smaller and try sending it again."

The limit of 40MB cannot be raised, because it is enforced by our mail services provider. If your contact needs to deliver a file larger than 40MB, you should enable web uploads for your inbox and direct them to upload through a web browser. If the message is large due to multiple attachments, have them send multiple emails with separate attachments to fit below the 40MB size limit per message.
