How do i do the above so these changes are printed out as changed in the incoming e-mail text. I know you can make these changes under mail settings but how do you save these changes. I tried it out and sent a message from one xfinity acct to another but the changes did not take hold. Thanks.
After you have made the changes, sign out of the account and back in again to get the changes to "take". It might take a couple of tries.
