The PGP Forwarding Server is a tool that allows users to send encrypted emails by receiving them on the server and automatically encrypting them before forwarding them on the user's behalf.
The software operates on the premise that it is not possible to encrypt the whole e-mail traffic due to real-world constraints. For instance, many of your relatives or business partners may not be proficient in using PGP. However, if you are a business owner, you can train your employees on how to use PGP and install the PGP Forwarding Server within your organization. Doing so would enable everyone in your company to communicate safely with your travelling salespeople, your accountant, your secretary, your tech department, and even yourself.
To communicate via safe channels with the server, a user needs to establish a connection either via PGP or SSH. If a user receives a message via PGP, the server encrypts the message and sends it over to the user. If a user wants to send an encrypted email, they can encrypt the message with the public key of the PGP Forwarding Server and send the email to the server's command interface using the "to" command. The server then decrypts the message and sends it in plain text to the intended recipient.
For those who prefer to establish a connection via SSH, one can configure their account such that the server places incoming messages into a POP3-mailbox. Then, the user can connect via SSH and use their regular email program to exchange emails. Similarly, to send an email via SSH, one needs to connect to the server via SSH and use any email program that uses SMTP to send emails normally.
In conclusion, PGP Forwarding Server is a fantastic software that enables users to encrypt their emails with ease. In the latest release, the developers added a nice intro web page.
