@msimerson I'm unsure whether the PR should be made here or in https://github.com/haraka/haraka-plugin-mailauth.

I'm not sure either. I've got a PR open here against this repo but maintenance appears to be thin.

Oh right, I had not seen your PR fixing the .address() call.

I opened the same PR on https://github.com/haraka/haraka-plugin-mailauth, since you probably have control over that one. The fork will start diverging, but I don't see a better option. 🤷‍♂️
