Several months ago I was having issues with delivery of email.  One of my troubleshooting solutions was to implement a read receipt code in terminal to determine which emails were going through and which were not.  I have since "fixed the glitch" and want to remove or reverse the terminal command but I have no idea how to do it.



This is the terminal command I used: 



defaults write UserHeaders '{"Return-Receipt-To" = ""; "Disposition-Notification-To" = ""; }'



Does anyone know how to remove a terminal command, disable it, or reverse the function?



Appreciate any help.

    Quit Mail, then in Terminal type:


    defaults read UserHeaders


    to check that the value of UserHeaders is what you expect. If there are additional UserHeaders beyond the ones you want to delete you'll need to add them back later. Now type:


    defaults delete UserHeaders


    All of your UserHeaders will be gone. If you need to add back some headers use:


    defaults write UserHeaders '{"foo" = "bar";}'


    Obviously you need to replace foo and bar with your values.
