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

  • added HKP keyserver key submit function to the gpg-mailgate-web script

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


  • Correctly displays attachments and general email content; currently will only display first part of multipart messages
  • Public keys can be stored in a dedicated gpg-home-directory (see Note 1 in INSTALL)
  • 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)
  • 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)
