CONFIGURATION
Set the %ContentTypes configuration variable to a hash of extension and desired content-type:
Set(
    %ContentTypes,
    (
        't'    => 'text/x-perl-script',
        'psgi' => 'text/x-perl-script',
    )
);
Microsoft Office
Older versions of IE often upload newer Microsoft Office documents with the generic application/octet-stream MIME type instead of something more appropriate. This causes RT to offer the file for download using the generic content type, which confuses users and doesn't launch Office for them. You can fix that by installing this extension and using the configuration below:
Set(%ContentTypes,
    'docm' => 'application/vnd.ms-word.document.macroEnabled.12',
    'docx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
    'dotm' => 'application/vnd.ms-word.template.macroEnabled.12',
    'dotx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.template',
    'potm' => 'application/vnd.ms-powerpoint.template.macroEnabled.12',
    'potx' => 'application/vnd.openxmlformats-officedocument.presentationml.template',
    'ppam' => 'application/vnd.ms-powerpoint.addin.macroEnabled.12',
    'ppsm' => 'application/vnd.ms-powerpoint.slideshow.macroEnabled.12',
    'ppsx' => 'application/vnd.openxmlformats-officedocument.presentationml.slideshow',
    'pptm' => 'application/vnd.ms-powerpoint.presentation.macroEnabled.12',
    'pptx' => 'application/vnd.openxmlformats-officedocument.presentationml.presentation',
    'xlam' => 'application/vnd.ms-excel.addin.macroEnabled.12',
    'xlsb' => 'application/vnd.ms-excel.sheet.binary.macroEnabled.12',
    'xlsm' => 'application/vnd.ms-excel.sheet.macroEnabled.12',
    'xlsx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
    'xltm' => 'application/vnd.ms-excel.template.macroEnabled.12',
    'xltx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.template',
);
