Article Title: configure the Mail server in LINUX. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

With the rapid development of the Internet, email has become an indispensable communication tool in people's life. Setting up an email system is relatively troublesome. You can check a lot of relevant information on the Internet. I am really grateful to so many enthusiastic netizens for making this network more powerful. I have always wanted to set up my own MAIL server. Due to the relationship between time and conditions, I had encountered a variety of problems when I had time to focus on it, with my belief that I would never give up, the mail server I set up was finally achieved. Of course, there are too many imperfections in the function. I will make up for it in the future to make it more powerful. This attempt has many feelings, and learning is a never-ending process,

Never stop at a place and stick to it. If you encounter a problem, you must solve it and find fun in your life. Below I will write my own installation process, not asking the majority of users to give advice, just asking myself to be able to three provinces. Believe in yourself, grow one day, and accumulate one day.
