This doesn't seem right. With Fedora 13:
$ yum info mailcap Installed Packages Name : mailcap Arch : noarch Version : 2.1.33 Release : 1.fc13 Size : 54 k Repo : installed
From repo : updates
Summary : Helper application and MIME type associations for file types URL : http://git.fedoraproject.org/git/mailcap.git License : Public Domain and MIT Description : The mailcap file is used by the metamail program. Metamail reads : the mailcap file to determine how it should display non-text or : multimedia material. Basically, 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. : : Also included in this package is the mime.types file which : contains a list of MIME types and their filename "extension" : associations, used by several applications e.g. to determine MIME : types for filenames.
$ yum --enablerepo=* list metamail Error: No matching Packages to list
$ yum --enablerepo=* provides */metamail No Matches found
Certainly, mailcap is used by programs other than metamail. But the description seems to imply that metamail is the primary user. So, where is metamail?
