1. A computer-implemented method of securely communicating e-mail messages, comprising:

  • receiving, from a server system providing a secure e-mail service, an e-mail message from a sender;

    receiving, from a user, an input to either forward or reply to the e-mail message;

    providing data corresponding to the user input to the server system;

    receiving a determination, by the server system, whether the user input comprises a request to forward or reply to the e-mail message via the secure e-mail service; and

    receiving a determination, by the server system, whether the user input comprises a request to forward or reply to the e-mail message via an e-mail service different from the secure e-mail service, the different e-mail service lacking security features of the secure e-mail service, whereinbased on a determination that the user input comprises a request to forward or reply to the e-mail message via the secure e-mail service, the server system proceeds with forwarding or replying to the e-mail message; and

    based on a determination that the user input comprises a request to forward or reply to the e-mail message via the different e-mail service, when enforcing a service-level option, the server system prevents the forwarding or replying via the different e-mail service and allows the forward or reply to the e-mail message to be sent via the secure e-mail service; and

    based on a determination that the user input comprises a request to forward or reply to the e-mail message via the different e-mail service, when not enforcing the service-level option, the server system notifies the sender that the security features of the secure-email service will be lost and sends the forward or reply to the e-mail message via the different e-mail service.
