The Little Brother Database

You can get the Little Brother Database (lbdb) from its sourceforge site (see 5). Set mutt to query the LBDB for addresses by adding the following to your muttrc:

set query_command="lbdb' '%s'"

The LBDB can query different sources of information to manage your addresses. See the Mark's Mutt Fan and Tip Page (Resources) for more information on how to configure the LBDB with mutt. In particular, the LBDB is a useful way for Mac users to get Mutt to interface with the Apple Addressbook that comes standard on Mac OS X. Vincent Danen does a tremendously good job at describing not just how to get this link to happen but also how to set up and use Mutt on Mac OS X in general. His website is listed in the Resources section of this guide.
