Penguin Greetings

The Penguin Greetings (pgreet) engine is a web-based greeting cards for LINUX and other UNIX-based systems written in Perl.

Penguin Greetings is template-based and shifts ecards to be more like email instead of web-only objects. For flexibility and security, a separate daemon does the emailing and stores data permanently on the server.

Features:
- Supports any number of ecard sites running on the same server. Each site is independent with its own configuration, database files, and HTML content. Localization/Internationalization is supported so that secondary ecard sites can be used to support multiple languages and regions. User ecard sites are supported.
- Greeting cards that function more like email. The announcement of the card includes the text of the card so that the recipient can reply to the message. The email of the author is included in the email reply-to field so that recipients can reply to the ecard using the reply feature of most email clients.
- Uses MIME multipart HTML formatted email to directly send complete ecards to recipients.
- Automated installation procedure, including: the installation of CPAN modules not included in Perl 5.8.0, localization of configuration files, and installation of applications, configuration files, and a default ecard website.
- Access to card creation can be limited to users stored in an htpasswd file on server for sites which want to have ecards available only to a particular group of people.
- A separate application daemon to handle such chores as: card scheduling for emailing on a particular date, purging of old cards after a certain date, and backup database files.
- A user agent separate from the user ID which the web server runs as for mailing and storing of data. If desired, ecards can be emailed under existing email accounts on server. Specific human users on the server can be given access to this feature via an access control list.
- Extensive configuration options. Including the location of configuration and data files, performance tuning, and content parameters.
- Based on standard Perl CPAN modules for portability and reliability.
- Extensive logging of daemon activities.
