Thanks for the review, Jeff! It's always good to see when your plugin is noticed :)

To address your suggestion regarding the "From" message, I have added some code to reflect the blog's domain in the message headers so that it is easier to identify the specific site that the notification is coming from. I just pushed it out to version 1.0.2 so you should see an update notification shortly.

Thanks again for the review! If anyone finds any bugs or has any suggestions, feel free to reach out to me!
