在Linux上安装邮件服务器涉及多个步骤,具体取决于你选择的邮件服务器软件。以下是一些流行的邮件服务器软件及其安装方法:
Postfix是一个流行的开源邮件传输代理(MTA),适合中小型邮件服务器。
更新系统包:
sudo apt update
安装Postfix:
sudo apt install postfix
配置Postfix:
/etc/postfix/main.cf
:sudo nano /etc/postfix/main.cf
myhostname = mail.example.com
mydomain = example.com
myorigin = $mydomain
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
重启Postfix服务:
sudo systemctl restart postfix
测试Postfix配置:
sudo postconf -t
Sendmail是另一个广泛使用的邮件服务器软件,但它的配置相对复杂。
更新系统包:
sudo apt update
安装Sendmail:
sudo apt install sendmail
配置Sendmail:
/etc/sendmail.mc
:sudo nano /etc/sendmail.mc
define(`SMART_HOST', `smtp.example.com')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl
define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
define(`confAUTH_OPTIONS', `A p')dnl
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confCACERT_PATH', `/etc/ssl/certs')dnl
define(`confCACERT', `/etc/ssl/certs/ca-certificates.crt')dnl
define(`confSERVER_CERT', `/etc/ssl/certs/your_server_cert.pem')dnl
define(`confSERVER_KEY', `/etc/ssl/private/your_server_key.pem')dnl
生成配置文件:
sudo m4 /etc/sendmail.mc > /etc/sendmail.cf
重启Sendmail服务:
sudo systemctl restart sendmail
测试Sendmail配置:
echo "Testing sendmail" | sendmail -t
Exim是一个功能强大的邮件传输代理,易于配置和管理。
更新系统包:
sudo apt update
安装Exim:
sudo apt install exim4
配置Exim:
/etc/exim4/exim4.conf

myhostname = mail.example.com
mydomain = example.com
myorigin = $mydomain
生成配置文件:
sudo econf /etc/exim4/exim4.conf
