email headers

[Developer8]

Does anyone know how to alter or remove extended email headers using sendmail? I'm doing a mass mailing on an opt-in customer database, and for security purposes, I don't want the name of the database server to show up in the email headers. Any suggestions?

Have you thought of formail?

I did some research and found that altering/removing extended email headers is not a good idea. Besides from being a red flag for spam, I would not be able to fake the Received Header.

i.e. If I were to add 3 fake Received Headers, my three would appear below the Received Header generated by the recipient's mail server.

I wanted to protect the name of my database server, but I've decided to go a better security route. Thanks for your help.
