Sendmail and Dovecot implement e-sister Services (2)

Continued: Sendmail and Dovecot enable Yimei Services 1)

When the email servers in both regions can forward emails in their own domains, you need to make other modifications to enable email sending for users in different regions.

Edit the sendmail relay file in the 163.com domain and sina.com domain again. /Etc/mail/access

Although it indicates that emails sent to other domains need to be retransmitted, how can we relay them? Who should I relay? If the email servers in the 163.com domain and sina.com domain in this test are connected to the Internet, you do not need to specify the region to which the MX is relay. Because it is connected to the Internet, the server will perform recursive and iterative queries to the root step through DNS, and finally find the MX in another region, so as to implement mail relay forwarding. However, in this test, we need to specify the email exchanger to which the relay is sent.

In order to achieve fast relay, it is best to do reverse DNS resolution, because the configuration in 163.com and sina.com is almost the same, here only the configuration in 163.com, sina.com can refer to the operation in 163.com.

After both configurations are complete, restart all services:
