GPGrelay

GPGrelay, developed by Andreas John, is a local relaying server designed for users looking to secure their email communications through encryption. The latest version, 0.959, of this open-source program aligns well with the needs of users working on Windows XP Professional. Previous versions, such as 0.9, have laid the groundwork for the robust features present in this iteration.

One of the standout aspects of GPGrelay is its ability to operate seamlessly with any Email-Client and remote servers, making it an essential tool in the Communication and E-mail Tools subcategory. When emails are sent, the program encrypts them and dispatches the encrypted mail to the SMTP-Server. Conversely, when receiving encrypted emails, GPGrelay handles the decryption process, so the email client never encounters encrypted messages. This feature is particularly beneficial for clients like Outlook Express, which lack built-in support for encrypted emails.

However, while this program ensures encrypted emails are transmitted securely, it's critical to note that emails are stored in a decrypted form locally. This means if someone gains access to the local environment where these emails are stored, they could potentially access them without much hassle.

The download and installation process for GPGrelay.exe is straightforward, and the fact that the program is available for free as an open-source application is a significant advantage for users looking for cost-effective solutions.

Pros:

• Seamlessly handles email encryption and decryption.
• Transparent operation with various Email-Clients and remote servers.
• Free and open source, ensuring no cost to the user.

Cons:

• Local storage of decrypted emails poses a security risk if local access is compromised.
• Currently supports only Windows XP Professional, which limits its user base.
