User reports that they can receive emails from the device with no issues, but when they reply to an email, or when they send a new email to the device they do not receive the email at the device.
By default emails received for devices are blocked unless they are sent from the SkyRouter interface.
The whitelist controls which email addresses are permitted to send emails to devices on the SkyRouter account. The Whitelist must be enabled and populated with entries in order for emails to be accepted to the device.
There are two whitelists; the auto-whitelist (automatically adds email addresses to the whitelist when the device sends emails to them) and the manual whitelist (must enter a comma separated list of email addresses.)
