There is no field other than X-CTCH-RefID in scanned e-mail header. Is this normal ? I just want to make sure the antispam feature is working properly.

bed . I know my message will come to you as a surprise. But don't
worry. All i hope is that you will not betray this trust and confident
i am about to impose on you. I thank God for his direction as regards
this mission. God want me to complete this mission hence, I got your
contact from the internet through a nursing friend so that you can help
me utilize this wealth the way I am going to instruct herein.

My husband earned these funds, Nine Million Two Hundred Thousands
United State Dollars ($9,200,000.00 USD) but he died in a plane crash
in 2010 and left everything behind for me and since i will join him
soon due to my ill health. Due to my infertility resulting from medical
problems I became barren. God has a reason for everything. I would want
you to contact my lawyer; he will inform you on what to do. Contact him
with the below details:

fulfillment of my last wish. Furthermore you will never have any
problem with the law as far as my lawyer is in concern. The most major
