When receiving an encrypted message for the first time, the Zero-Download / "My Private Post" portal will ask you to register your email address with the service. At the end of the registration process, a verification email will be sent to verify your address. However, the verification email is not received.
This happens because, under certain circumstances, the email cannot be delivered, or is blocked by your service provider.
To fix the issue, below are some of, but not limited to, the things the you can do:
- Check if the verification email was sent to the spam folder.
- Contact your mail admin or service provider to:
- Configure the geo-fencing. Geo-fencing only allows to receive emails from certain sources, which could be limited to pre-defined subnets, service providers or countries. You can expect the verification emails to be sent from the following IP addresses: 126.96.36.199 & 188.8.131.52.
- Check the content filters for false positive detections.
