I'm unable to use npm to run Haraka. What is the alternative?
If you are unable to use npm to install Haraka, you can run from git by following these steps:
First clone the repository:
$ git clone https://github.com/baudehlo/Haraka.git
$ cd Haraka
Edit config/plugins and config/smtp.ini to specify the plugins and config you want.
Finally run Haraka:
$ node haraka.js
