gpg-mailgate

gpg-mailgate is a content filter for Postfix that automatically encrypts unencrypted incoming email using PGP or S/MIME for select recipients.

For installation instructions, please refer to the included INSTALL file.

Features

• Correctly displays attachments and general email content; currently will only display first part of multipart messages
• Public keys are stored in a dedicated gpg-home-directory
• Encrypts both matching incoming and outgoing mail (this means gpg-mailgate can be used to encrypt outgoing mail for software that doesn't support PGP or S/MIME)
• Easy installation
• gpg-mailgate-web extension is a web interface allowing any user to upload PGP keys so that emails sent to them from your mail server will be encrypted (see gpg-mailgate-web directory for details)
• people can submit their public key like to any keyserver to gpg-mailgate with the gpg-mailgate-web extension
• people can send an S/MIME signed email to register@yourdomain.tld to register their public key

This is forked from the original project at http://code.google.com/p/gpg-mailgate/
