An updated mailcap package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The mailcap package contains the mailcap file, which is used by the metamail program. Metamail reads the mailcap file to determine how it should display non-text or multimedia material. mailcap associates a particular type of file with a particular program that a mail agent or other program can call in order to handle the file. Mailcap should be installed to allow certain programs to be able to handle non-text files.
Prior to this update, the mime.types database did not contain the WebM MIME type (video/webm). The problem has been resolved in this update by including the MIME type in the database.
All users of mailcap are advised to upgrade to this updated package, which fixes this bug.
