uncsv is a filter command converting the lines of a CSV file into a non‐escaped, non‐quoted delimited file (pipe by default). csv is the opposite of this command; it takes an un-quoted stream of values, separated by the delimiter of your choice (default: pipe ’|’) and produces a "standard" CSV file. Both tools avoid end‐of‐line character politics and will leave these untouched.
Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OS X to manage email communication in a private way, without relying on online services (in fact, encouraging users to store email locally). It mainly features a system for mailinglist filtering, address-book integrated whitelisting, and long-term email storage and archiving with functions for fast search and usage statistics. It makes internal use of customized versions of popular Unix tools like Mutt, Fetchmail, Procmail, Mairix, and Msmtp.
Urban Lightscape is a photo filter for exposure correction, localized brightness adjustments, dodging and burning, and the introduction of synthetic lighting to a photo. A simple "double-click-and-drag" paradigm is used to place control points on a photo, and clever edge detection localises and interpolates lightness adjustments around and between these points. Results are rapid, with additional controls for more subtle refinements.
Clement is an email server application. Its main function is to block unwanted mail (spam) as soon as possible in the email exchange process. It accepts or rejects email while the SMTP session, initiated by the email sender, is still pending, accepting legitimate email messages without the need to return an error status to non-existent or "borrowed" return address later. Clement can operate in two modes, either as a standard MTA (as sendmail, Postfix, Exim, Exchange, etc.) to store email in the recipient's own area, or to transmit the mail to an another SMTP server acting as smart spam filtering device. Each email domain name Clement knows about can be treated in one of these two modes depending on the group to which the domain name has been set. Each message is verified by a virus scanner (ClamAV) while the SMTP connection is still open, but the refusal of mail and the reason for refusal is notified to the actual sender. Mail management is done via a Web interface and can be delegated to three administrative levels (Root-Admin, Group-Admin, Domain-Admin). Standard users can access their own logs (sent email status, email rejected, quarantined email, etc.). With this interface, the user can handle the rejection and acceptance of mail. Users who are level "Admin" can access the session logs (via the Web interface). Clement uses a SQL database (PostgreSQL, MySQL) to store and manage logs, user profiles, and dynamic management of directives concerning the sender-receiver relationship.
MailChariot's only mission is to get your incoming email (for example from /var/spool/mail), filter it through a spam filter, and put it into a spam or ham mailbox. If you don't agree with the spam filter's decision, you can move it to the notspam or notham mailbox and MailChariot will mark the message as ham or spam respectively. This design is mail client agnostic. It is ideal for use on shared hosts where the provided spam filtering is not effective enough.
Baruwa (Swahili for letter or mail) is a Web 2.0 MailScanner front-end. It provides an easy to use interface for managing a MailScanner installation. It is used to perform operations such as releasing quarantined messages, spam learning, whitelisting and blacklisting addresses, monitoring the health of the services, etc. Baruwa is implemented using Web 2.0 features (AJAX) where deemed fit. Graphing is also implemented on the client side using SVG, Silverlight, or VML. It includes reporting functionality with an easy to use query builder. Results can be displayed as message lists or graphed as colorful and pretty interactive graphs. Custom MailScanner modules are provided to allow for logging of messages to the MySQL database with SQLite as backup and for managing whitelists and blacklists.
Synspam uses Netfilter NFQUEUE to catch the source IP address of any machine connecting to your mail server, running multiple tests against it (RBL check, regexp on the reverse name, etc.) before forwarding the connection to the MTA. In order to have as few false positives as possible, a scoring system is used. If the source IP address is believed to be a spammer IP address, the connection can be dropped. There is a dry run mode if you just want to test it, which is the default.
