+Mutt's mime&lowbar;lookup list specifies a list of mime-types that should not
+be treated according to their mailcap entry.  This option is designed to
+deal with binary types such as application/octet-stream.  When an attachment's
+mime-type is listed in mime&lowbar;lookup, then the extension of the filename will
+be compared to the list of extensions in the mime.types file.  The mime-type
+associated with this extension will then be used to process the attachment
+according to the rules in the mailcap file and according to any other configuration
+options (such as auto&lowbar;view) specified.  Common usage would be:
+<tscreen><verb>
+mime-lookup application/octet-stream application/X-Lotus-Manuscript
+</verb></tscreen>
+
+In addition, the unmime&lowbar;lookup command may be used to disable this feature
+for any particular mime-type if it had been set, for example, in a global
+muttrc.
