oSpam is an anti-spam system based on Perl, qmail, and, optionally, vmailmgr. It features "one-day" email addresses for usenet postings: after a delay, the mails sent to your address will be put in quarantine waiting for a confirmation, or/and can be used as your main email address: all your contacts are listed in a file. If somebody which isn't in the list sends you an email, he will get a small and unique confirmation request, and then the email(s) will be delivered transparently.

JFetch is an application to download your email through protocols like POP3 and IMAP. The decision of whether to download a mail or not is made through a sequence of filters.

Parse Direct User Access Terminal mitigates information overload from aviation weather brief downloads. The USA Federal Aviation Administration (FAA) Direct User Access Terminal (DUAT) standard, outlook, and abbreviated weather brief are broken into a hierarchy of files. Each file contains one METAR/NOTAM/PIREP/TAF/etc. Options allow input of HTML source or text, output of HTML or text, and a flat directory or multi-level directory. As separate files, NOTAMS/etc. scripts can quickly identify changed information, or prioritize for relevance. Parsing is lossless and the complete original text can be reconstructed using cpp(1).
