smtp简单邮件传输
1.建立dns(mail.mail.com和liunx.linux.com)
/etc/named.rfc1912.zones
/var/named/liunx.com.zone
/var/named/mail.com.zone
2.vim /etc/postfix/main.cf
默认设定:
myhostname = linux.linux.com
mydomain = linux.com (域名)
myorigin = $mydomain (邮件地址后缀名)
mydestination = $myhostname,$mydomain, localhost
3.mail root@mail.mail.com(向其他机器的用户发送)
postsuper -d mail-id /*清除未发出去的邮件
postqueue -f /*刷新收邮件箱
vi /etc/aliases:(系统级别)
admin root
postalias /etc/aliases
mail admin (实际收信人为root)
more: :include:/etc/moreusers
vi /etc/postfix/generic:(配置文件级别)/*隐藏实际域名
root@linux.com rensiyuan@qq.com
postmap generic /*通用加密
postconf -e "smtp_generic_maps = hash:/etc/postfix/generic"
systemctl restart postfix.service
telnet ip /*远程控制电脑发邮件
mail from:root@westos.com
rcpt to:root@linux.com
