Note

This field is only useful if you want replies to your mail to go somewhere else than your regular email address, e.g. if you are using this identity to send messages from an email address that cannot receive messages. Note that some mailing lists overwrite this header field with their post address to make sure that replies go to the list instead of individuals. So the usefulness of this field is very limited and it should only be used in rare cases.
