Dave,

You might want to re-read the part about wrong address. If the customer enters the wrong address (customreATgmail.com vs customerATgmail.com), then the database would contain the wrong address when used to resend the email ($to_address).

If the mod does not have the feature, it would be nice to have the update of a customer also update the $to_address if the customer's email is changed.

Not familiar with the mod. Perhaps the DEVELOPER_OVERRIDE_EMAIL_ADDRESS takes care of this?
