Those are headers, which provide information or meta-data about the actual message. Standard headers are defined in RFC 5322. Every mail server the message passes through can also add its own custom headers for information; custom headers must have a name prefixed by the string "X-". For instance: > To: linux-india-help@lists.sourceforge.net is the standard To: header, which tells your mail client whom the message was sent to. On the other hand: > X-Originating-IP: [216.34.181.88] is a custom header probably inserted by Yahoo which gives the original IP address the message was received from. Since each mail server can insert its own custom headers, there is no standardisation on those. However, some are so common that they have become de-facto standards. Please see section 3.6 in RFC 5322 for more information about the standard mail headers.
