mime_content_type() is deprecated and does not work like our funtion. The 
former does an extention-to-type mapping, the latter retrieves the mime 
type from the content header and is therefore working only for http 
resources. The extention-to-type mapping takes place in 
t3lib_htmlmail->getExtendedURL.
