SpamAssassin Rule: MSGID_FROM_MTA_HEADER

Standard description: Message-Id was added by a relay

Explanation

The Message-Id header appears above at least one Received header in the message. This is a good indication that the Message-Id was generated by a relay, rather than by the user agent. This may be an indication of poorly behaved mailing software.

Further Info

The default scores for this rule can be found in the online list of tests.

Message-Id is defined as an optional field that should be present ( RFC 2822 sec 3.6.4).
