How to Install/Setup Nginx Mail Proxy Server on GCP (Proxy Email, SMTP, POP3, IAMP)

Nginx is open source for Mail proxy, web serving, reverse proxying, caching, load balancing, media streaming, and more. NGINX is highly scalable as well, meaning that its service grows along with its clients traffic. NGINX can proxy IMAP, POP3 and SMTP protocols to one of the upstream mail servers that host mail accounts and thus can be used as a single endpoint for email clients. This tutorial shows how to deploy and install a mail proxy on Google GCP.

This video demonstrates how to setup Nginx Mail Proxy Server on Ubuntu on GCP – Google Cloud Platform.
