email2sms is a filter written in Perl which converts an e-mail into a form suitable for sending as an SMS message. Its main advantage over the alternatives is that it uses the CPAN module Lingua::EN::Squeeze to compress the text down to as little as 40% of its original size, so you can get much more of your e-mail into the 160 character limit imposed by SMS. It is fully MIME compatible, and has many configurable options, including removal of quoted text. Ideal for use with procmail. A Perl script for sending the output to a typical e-mail to SMS web gateway is included.
eud2mbox is a conversion utility to convert Eudora mailboxes (already mostly mbox format) to real mbox-formatted mailboxes, removing all the html/x-flowed and other garbage. It also reads the TOC file and properly inserts both Status: and X-Status: headers so that mailers like mutt/pine/elm can properly tell what messages are read, new, replied, etc.
fmscore is a Perl5 program which uses the Mail::Freshmeat Perl module to parse freshmeat daily e-mail newsletters, and then rank them by interest according to highly flexible user-supplied ranking rules. Articles below a specified score will be removed from the output. fmscore is intended/suitable for use as a procmail filter.
getmail is intended as a simple, secure, and reliable replacement for fetchmail. It retrieves email (either all messages, or only unread messages) from one or more POP3, SPDS, or IMAP4 servers (with or without SSL) for one or more email accounts, and reliably delivers into qmail-style Maildirs, mboxrd files, or through external MDAs (command deliveries) specified on a per-account basis. getmail also has excellent support for domain (multidrop) mailboxes, including delivering messages to different users or destinations based on the envelope recipient address.
Install-Sendmail will configure Sendmail and Fetchmail on your machine. This Perl script can be used to setup a mail server for a simple network or it can configure email on a dial up machine. All you need to know is your email address, login name and password and optionally, the IP addresses of your network.
