In Linux, the service used to send mail is postfix, the service used to receive the message is pop (110 port), IMAP (143 port), and the software used is dovecot. The following two hosts are configured to start the message and manage the message.

For demonstration convenience, the host names of the two hosts are set to "mailqq.qq.com", "mail163.163.com" respectively.

B, "Vim/etc/named.rfc1912.zones". The content in the input.

C, "Vim/var/named/qq.com.zone", "Vim/var/named/163.com.zone". Configure the DNS domain name file.

After completing the service restart, enter "Dig-t mx qq.com", "Dig-t mx 163.com" To see if the configuration was successful.

Enter "Vim/etc/resolv.com" on both hosts and edit "NameServer 172.25.254.202" in it.

After completing the above steps, the domain name configuration is complete.

2. Sending and receiving mail

After completion, restart the service postfix, and make the same configuration on the other host, then you can send and receive mail.

Messages can also be managed remotely through mutt. The following configuration is required on the mail server to be managed separately.
