1. 配置epel源(exim包位于EPEL软件源中)
CentOS7
# cat > /etc/yum.repos.d/epel.repo << EOF
[epel]
name=Extra Packages for Enterprise Linux 7 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-7&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=0
EOF
CentOS6
# cat > /etc/yum.repos.d/epel.repo << EOF
[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
#baseurl=http://download.fedoraproject.org/pub/epel/6/$basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-6&arch=$basearch
failovermethod=priority
enabled=1
gpgcheck=0
EOF
2. 禁止postfix
# service postfix stop
# chkconfig postfix off
3. 安装exim
# yum -y install exim
4. 将exim设为默认的MTA
# alternatives --set mta /usr/sbin/sendmail.exim
5. 修改exim配置文件
# vi /etc/exim/exim.conf #几个参数
primary_hostname = mail.linuxeye.com #查看源邮件时显示Received: from mail.linuxeye.com,如果不指定直接取操作系统的hostname
domainlist local_domains = @ localhost : localhost.localdomain :mail.linuxeye.com
domainlist relay_to_domains = linuxeye.com #允许通过改主机发送邮件的域名
hostlist relay_from_hosts = 127.0.0.1 : 192_32G : 192.168.0.0/16 : #允许那些客户端主机发送邮件,如本地使用这台服务器发送邮件时,即需要添加本地出口ip地址(公网地址)
6. 测试
# yum -y install mailx
# date | mail -r [email protected] -s 'exim test' [email protected]
# tail -f /var/log/exim/main.log #exim日志文件
ps:
如果不指定-r(发邮件地址),且你的主机名不是xxx.com,可能会报如下错误:
SMTP error from remote mail server after MAIL FROM:
错误是550 MI:IMF 发信人电子邮件地址不合规范
经验:
强烈建议用网易企业邮箱,如果自己搭建邮件服务器做发邮件,又设置QQ企业邮箱做本地收发服务器会出现地址未验证问题
