    Sanspam

    Interactive spam removal utility

    ...Sanspam is inspired by Save My Modem by Enrico Tasso and SpamX by Emmanual Vasilakis, which are two simple, easy to set up tools that I used to use, but aren't maintained any more and require too much work to justify update. Sanspam supports POP and IMAP accounts, and also supports SSL for secure connections. This is more suited to those who use e-mail clients and prefer to download messages to their computer, but also prefer not to allow spam, or potentially harmful messages to be downloaded at all. Instead of running a risk having it downloaded by the e-mail client, Sanspam allows you to delete it on the server, without being exposed to any attachments or e-mail content.

    EESST

    Email Exchange of Secondary School Transcripts

    This package implements a common format for exchanging secondary school academic transcripts via electronic mail. MIME and OpenPGP email standards are applied to enable secure communication of transcripts directly from each student to his or her chosen recipients without intervention or monitoring by any third-parties. Thus, using the defined format better protects student privacy and independence than does current practice. Because transcripts are digitally signed by the originating school official, transcript recipients can independently verify that transcripts received directly from students have not been altered in transit.

    ...It has been ported to all major architectures and been used as a template for ports to different computer and human languages. This is very mature and stable code. Although this comes from a project that was constrained by export controls and is used in secure systems, it is not security code per-se. I have therefore altered the 'Export Controls' category.
