GPGMail: Apple Mail plugin to secure e-mail sending

GPGMail is an open-source plugin for Apple Mail that provides a secure way to encrypt and send e-mails. With GPGMail, users can encrypt their mail before sending it, ensuring that sensitive information remains confidential. The plugin uses the PGP standard to sign, verify, encrypt, and decrypt mails.

One of the key features of GPGMail is its ability to alert the receiver if any changes have been made to the original message. This adds an extra layer of security and helps ensure the integrity of the communication.

However, it's worth noting that some Mail users have experienced compatibility issues with GPGMail after OS X updates. For example, the last update to Snow Leopard caused problems with GPGMail's functionality.

Overall, GPGMail is a reliable plugin that gives Apple Mail users peace of mind when it comes to secure e-mail sending.
