The AmavisNewSQL SquirrelMail plugin gives you per-user control of a subset of SpamAssassin settings which are stored in a database. It also allows you to use a quarantine database for questionable mail. This plugin was designed with enterprise use in mind, and differs from other plugins in that it works with amavis-new rather than SpamAssassin directly. Most of the code lives in an external class that you can reuse in your own admin tools. It even has support for SOAP calls to perform common tasks.

Rbmhshow seeks to provide an efficient and lightweight MIME- capable command-line MH mail environment, leveraging existing applications wherever possible. It is a flexible alternative to the standard MH mhl and mhshow applications. MIME messages are displayed in a single continuous less session, with non-plaintext components (e.g. HTML, Word, JPEG) converted to text by the appropriate utility. PGP and S/ MIME signatures are automatically validated, headers and separators are coloured, and the less prompt displays information about the current mail. Command keys are then provided within less to perform common operations, such as replying to, refiling or deleting mail, moving to the next message, etc.

WapReader supports base64 and quoted-printable mail encodings and all charsets supported by iconv().
MuseSig is an email signature generator. The script takes an ID file (your contact information) and combines it with a quote taken from a local collection of quotes to produce a new signature file. Command line options allow selection of output file, the format to use (one of two types), and various other options. Quote files are plain text and new quotes can be added just by adding a new file to the quote directories.
