Explanation

The mail header does not contain a To: line.

Further Info

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

The To: header is described in RFC 2822 sec 3.6.3 - note that it is not a mandatory field, but it is considered unusual for MUA software not to add it.
