These are the two real tests the E-mail failed (the weighting tests aren't
"real" tests, since they just rely on other tests). The BADHEADERS test
indicates a *serious* problem with the mail client used to send the E-mail
(the E-mail isn't RFC-compliant). The SPAMHEADERS test is one that a fair
amount of auto-generated E-mail from websites will fail (if they are poorly
designed).

And, a missing To: header and Date: headers.
Is your customer a funny guy and sending these E-mails via telnet? I've
never seen a mail client that left out all those headers, nor have I even
seen the worst web site send out E-mail missing all three headers!

The "MAIL FROM:" line in the IMail SMTP log file is the "return address"
from the SMTP envelope, which is not part of the headers.

Yes, I have an idea: Tell him to scrap CRCS. It was probably designed by
someone who had never used the Internet before. :) Seriously, though, it
is severely broken. Many mailservers will add these headers if they are
missing, which explains why other people see those headers. The reason
they receive it is probably because they don't have spam filtering
software. <G>

The short answer is that you either changed the weight for the SPAMHEADERS
test to be 13, or other tests are failing as well. For a long or more
detailed answer, this would best be brought to the Declude JunkMail mailing
list.
