From Gentoo Wiki
The above .mailcap example tells Mutt what to do to "view" msword and pdf files. For the former it should run a program called antiword, for the latter the program pdftotext (emerge app-text/poppler). You can go wild with these to for example display rendered HTML (give app-text/vilistextum a try), render vcards, or show ASCII representation of attached images. All you need to do is define how to call the program in your .mailcap, and tell Mutt to try to view it inline using the auto_view directive.
