Plugin-based app for rapid searches. Maigret is a plugin-based application that allows for rapid searches. The actual release comes Mail Search: a plugin that allows you to search the contents of any e-mail stored in the commonly-used canonical mbox format. Automatically, Mail Search manages the mailboxes of the most widely used e-mails applications, like Mail, Eudora and Mozilla. Mail Search is very simple to use, open the application, type the word to search for and click on the search button. That's it! If you use another e-mail application that does not handle e-mail directly in the mbox format, you must export them in the right format first and then add them in the list to search.Mail Search also allows you to search using regular expressions patterns.
