Sendmail server configuration (RedHat6.2) -- Linux Enterprise Application-Linux server application information. For details, refer to the following section. Sendmail server configuration (RedHat 6.2)
I. Prerequisites
First, you need to install sendmail. If you choose to install it all during Linux installation, sendmail is already in your system. If not, install it.
Second, your DNS must be correctly configured and complete; otherwise, the sendmail service may not run properly.
If your system is installed as described above, the configuration of the sendmail service can be said to be very simple. For details about DNS configuration, please refer to the article on this site.
Ii. configuration process
1. Modify the/etc/mail/access File
As shown below: domain.com RELAY // "domain.com" is the name of your domain
192.168.0 RELAY // allow machines with 192.168.0. * to send emails through your machine
Then enter the following command to convert:
Makemap hash access. db <access
2. Modify or create a file:/etc/mail/relay-domains:
192.168.0
In this way, you can. This configuration may cause many problems. The above is the simplest method I have summarized after more than a dozen installation and configuration of linux. I hope it will help you. Note that your DNS must be correct, otherwise sendmail will not work well.
