The AMC Mail Client is a mail client striving to be a robust, fully gnome-compliant mail reader. However, the AMC Mail Client differs from other mail clients in that it attempts to utilize existing tools for mail retrieval, sending, and filtering, (fetchmail, sendmail/smtp, procmail). By not going through the process of reinventing the wheel, the AMC Mail Client starts out as a fully equipped client that inherits all of the features of these existing tools.
AMaViS (A Mail Virus Scanner) scans e-mail attachments for viruses using third-party virus scanners available for UNIX environments. It resides on a UNIX (Linux) machine and looks through the attached files arriving via e-mail, generates reports when a virus is found and sets the delivery on hold.
AMaViS-ng is a modular rewrite of amavisd and amavis-perl. It scans email for malicious code inside attachments and archive files, stopping delivery if malicious code is found. It supports integration of several third-party virus scanners and integrates nicely into several MTA setups. Unlike amavis-perl and amavisd, there is no need for build-time configuration.
AbulÉdu is a Ubuntu-based distribution for primary schools. It is currently in French but most of the tools can be translated. An AbulÉdu server can handle Mac, Windows (samba), GNU/Linux and X terminal (with LTSP) clients. The server acts as a central gateway for Web, mail, and printing, and facilitates the management of classes, pupils, and teachers. Everybody can publish Web pages on an intranet using Apache and all administration tasks are performed using a browser. The result is that a teacher who is not a computer specialist can install and manage a school network.
Active Spam Killer (ASK) protects your email account against spam by confirming the sender's email address before actual delivery takes place. The confirmation happens by means of a "confirmation message" that is automatically sent to all "unknown" users. Once the sender replies to that message (a simple reply will do), future emails from that person will be delivered immediately. You can also specify (regexp) addresses to be immediately accepted, rejected (with a nastygram) or ignored. The package also includes a utility to scan your old mailboxes and generate a list of emails to be accepted automatically.
