== SpamAssassin Rule: MISSING_HEADERS ==

''Standard description:'' Missing To: header

=== Explanation ===

The mail header does not contain a To: line.

=== Further Info ===

The default scores for this rule can be found [[http://spamassassin.apache.org/tests.html|in the online list of tests]].

The To: header is described in [[http://tools.ietf.org/html/rfc2822#section-3.6.3|RFC sec 3.6.3]] - note that it is not a mandatory field, but it is considered unusual for MUA software not to add it.
