Config lost after executing yarn

[kino90]

Hello! Thanks for this useful repo :)
I was using it today, but I had a problem with some yarn package and run a yarn install, which erased my already customized nodemailer.config.js ..

It would be cool if the postinstall script could ask something like "I found a nodemailer.config.js, do you want to reset it? (y)/n " only if there is actually a file named that way (so not after the first install) 👍

Hi - I'm glad you find this project useful :)

I wrote this when I was focused purely on churning out email campaigns at my previous job and haven't really given this much thought after that.

If you are able to implement the solution yourself, please fork and submit a PR and I'll merge it in.

Thanks!
