Thanks for a great library. I can't seem to find any info on authentication, is this supported?
As an example, I'm trying to implement a basic form post with user authentication for this service:
https://documentation.mailgun.com/api-sending.html#examples
Are there any docs or examples about how to use the curl equivalent of
curl -s --user 'api:YOUR_API_KEY' https://domain.com -F from='User <mailgun@YOUR_DOMAIN_NAME>'
