Why We Do Not Recommend Running Mail Server Software For Ordinary Works

 

Although Hosted Mail Server Software provides privacy, in very short, it is very difficult to not become a target of the spammers. Security of the server is a big concern. Networking connection of web host better be 1Gbps to 10Gbps, using a professional DNS management (like Dyn) is almost mandatory. It is really not cost and effort effective when solutions like SendGrid exists.
