Exim自己搭邮件服务器

Install and configure Exim

Issue the following commands to update your package repositories, upgrade your system, and install Exim:

$apt-get update
$apt-get upgrade
$apt-get install exim4-daemon-light mailutils

Now you’re ready to configure Exim for local or remote mail service. Enter the following command to start Exim configuration:

$dpkg-reconfigure exim4-config

The user interface will be displayed to let you configure many parameters. Choose these config options:

1. General type of mail configuration: internet site; mail is sent and received directly using SMTP
2. System mail name: Enter FQDN, ie. hostname.yourdomain.tld
3. IP-address to listen on for incoming SMTP connections: 127.0.0.1 for local, <leave blank> for remote connections
4. Other destinations for which mail is accepted: FQDN; local hostname; localhost.localdomain;localhost
5. Domains to relay mail for: remote server ip
6. Machines to relay mail for: <leave blank>
7. Keep number of DNS-queries minimal (Dial-on-Demand)? No
8. Delivery method for local mail: Maildir format in home directory
9. Split configuration file into small files? No

All the parameters you configure in the user interface are stored in /etc/exim4/update-exim4.conf file. If you wish to re-configure, either you re-run the configuration wizard or manually edit this file using your favorite editor. Once you configure, you can run the following command to generate the master configuration file:

$update-exim4.conf
# You can run the following command to restart Exim4 daemon.
$service exim4 restart
