BADHEADERS
** Declude All Versions - Global.cfg
This test type looks for non-RFC-compliant headers that
are common in spam, and rarely (if ever) found in E-mail from legitimate mail
clients. This test can catch about 50% of all spam, with the only false
positives being mail that comes from broken mail clients. This is a very good
test to use.

Examples of Code Violations
8020000c
Indicates that the Date: header was not part of the E-mail. The
Date: header is required, and added by all E-mail clients that we know of. If
the Date: header isn't present, it can easily cause the mail to "disappear" in
an inbox that is sorted by date (as most
are).
a0040103
Message-ID:
<3B890295.12230.ABAE76@localhost>
The Message-ID: header must have
a fully qualified domain name after the "@" sign ("localhost.mydomain.com" would
qualify, but 'localhost" would not). A fair number of spammers will use a
Message-ID: header with "@localhost" in it, in an attempt to conceal their
identity.
