Configuring SMTP for Email

Hello there. I have configured the email backend for sending out email so the contact form is working now. Setting up VPS to host using Nginx with SQLite is good enough for this website. Moving forward, I will be migrating to PostgreSQL so that I don't need to keep bringing my database down to dev and then push it back to production. Also, next integration will be integrating the WYSIWYG editor so that the blog post can have more html tags and more intuitive to see and read.
