1. 配置epel源(exim包位于EPEL软件源中)
- # 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 no-reply@linuxeye.com -s 'exim test' lj2007331@163.com
- # 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。
