What it does
NoSpamProxy Encryption is a gateway-based product for managing email encryption and certificates. It documents S/MIME, PGP, Outlook controls and PDF Mail for recipients without compatible encryption software.
NoSpamProxy Encryption centralizes certificates and keys at the gateway, with optional controls inside Outlook. That can suit an organization that wants consistent protection without configuring every sender’s keys independently.
PDF Mail is the documented fallback for recipients without S/MIME or PGP. The administrator can choose whether to protect attachments or the full message and how a password is set. This is a delivery tradeoff to plan with recipients, not the same experience as standard encrypted mail.
Strengths
- S/MIME and PGP key administration can be centralized.
- An encrypted-PDF fallback supports recipients without standard encryption tools.
- Outlook controls are documented.
Best for
- Mail administrators who need certificate-based encryption and a fallback delivery route
