Title: Remove custom headers for sender/reply behavior

There's no way to remove custom headers, and some large mail server providers do not allow custom sender/reply-to headers (Amazon Web Services SES, for example).

It may be best to add a "deleteCustomHeader" function on the Email, but this update makes the module usable in these cases in the meantime.
