Whitelisting guide

Depending upon the configuration of your environments, you may need to whitelist the following items for successful use of Mailock.


Email filtering

Secure emails that are composed and sent by users signing in to the www.besecuremail.com website will come from securesend@beyondencryption.com.

Mailock also uses verification emails during the user registration to prove that the registrant has access to the email address being registered and notification emails to provide an audit trail to the sender when messages are opened by the target recipient. These emails will be sent from notifications@beyondencryption.com.

To aid the successful delivery of Mailock messages, please ensure that any email filtering applied allows emails from both addresses.


Web filtering

Please ensure that any web filtering allows access to the following URLs, which are required for the normal operation of the Mailock system.



Our enterprise website is where all details about the system can be found.


Our main web portal is where users may register, read, and compose secure emails directly from within a browser.


Our core API is used by the Outlook Add-In and web portal.
