A way to change the from address?

You can use plugins like https://www.ads-software.com/plugins/cb-change-mail-sender/ to change the address which is used by outgoing mails of WordPress.

However – for future updates I’ll add an option in the backend to set the sender adress for comment reply notifications as well: https://github.com/arnowelzel/worpdress-comment-reply-email-notification/issues/37

Thanks.

By the by, I have a question about the basic reason for your plugin. I notice at one other WordPress site I run that there already seems to be a way to indicate you want to receive replies to comments by email. Apparently it comes from JetPack. Do you consider this plugin as an alternative to JetPack?

I like the option to have the “Notify me via e-mail if anyone answers my comment” checked by default.

Thanks.

Yes, I consider this as an alternative to Jetpack. Not everybody wants to use Jetpack as service which requires registration (also see https://jetpack.com).
