Maildrop Spam Filter is a Maildrop script file for identifying and adding a header to possible spam. Using the header, suspected spam can be filed in a low-priority mail folder or trashed.

Demoroniser is a Perl script which attempts to fix the gratuitously incompatible HTML generated by Microsoft applications. Many Microsoft programs use an 'enhanced' version of Latin-1 with extra characters like quotation marks and dashes. Sometimes people paste these characters into supposedly ASCII or Latin-1 web pages, resulting in pages that don't display properly on non-MS platforms. Demoroniser replaces these MS characters with standard ASCII equivalents. It also fixes up wrongly nested tags generated by HTML export in some MS applications.
Respell converts English text between the American, British, and Canadian spelling conventions. It prompts the user for cases where more than one target spelling could be chosen for a source word. It can also create a 'universal' spelling which can be automatically converted to any of the three without loss of information.
