I did a quick test to ensure the security of my email communication, as follows:

1. I sent an email from my digital-certificate signed email account ( to an alternate non-signed email account (, with the message body "asdf."
2. In my yahoo account, I redirected this email to a 3rd alternate non-signed email account (, adding this text to the message body: jkl;
3. In my gmail account I received the redirected email with the altered message body, yet still showing signed by

It appears to me that this digital signature is not accurate, because the message was altered by the recipient and then re-directed to another email.

I've emailed Thawte a couple times and they haven't responded.
