I was looking into using Nodemailer in an application of mine and was wondering when isn't it free and requires a license.
I have tried reading over the doc but all the legal stuff goes over my head. On the pricing page they have this:
Nodemailer is available under a more restrictive license without a fee, so you are free to test Nodemailer before actually buying anything.
But don't really list the restrictions that I can find so not sure what they are.
