10 systemctl restart named

11 systemctl stop firewalld.service

12 systemctl disable firewalld.service

 

 

基本电子邮件发送

 

1)postfix定义:

postfix提供smtp协议用来投递邮件,默认端口为25,日志在/var/log/maillog

MDA:“邮件发送代理“

2)重要的Postfix配置指令

1 myorigin :

重写本地发布的电子邮件,使其显示为来自该域。这样有助于确保响应返回入站邮件服务器

默认:myorigin = $myhostname

2 inet_interfaces:

控制Postfix侦听传入电子邮件的网络接口。如果设置为loopback-only,仅侦听127.0.0.1和::1,

如果设置为all,则侦听所有网络接口。还可以指定特定地址。

默认:inet_interfaces = localhost

3 mydestination:

收到地址为这些域的电子邮件将传递至MDA,以进行本地发送。

默认:mydestination = $myhostname, localhost.$mydomain, localhost

4 mynetworks

IP地址和网络的逗号分隔列表(采用CIDR表示法)。这些地址和网络可以通过此MTA转发至

任何位置,无需进一步身份验证。

默认:mynetworks = 127.0.0.0/8

 

3)邮件发送

发送邮件端:

 

1 vim /etc/postfix/main.cf###编辑postfix的主配置文件###

 

内容:

116 inet_interfaces = all###25端口开启的网络接口默认情况下,Postfix仅侦听来自本地主机的传入电子邮件。若要重新配置postfix以接收从远程主机发

送的本地邮件,必须设置inet_interfaces = all###

76 myhostname = westos-mail.westos.com###指定mta主机名称###

83 mydomain = westos.com###指定mta的域名###

99 myorigin = westos.com###指定邮件来源结尾(@后面的字符内容)

164 mydestination = $myhostname, $mydomain, localhost###接受邮件结尾字符的指定#

 

2 systemctl restart postfix.service###重启服务###

3 systemctl stop firewalld###关闭防火墙###

4 mail root@qq.com###发送邮件###

Subject: hello

hello

.###以“.”表示结束###

EOT

5  mailq(或postqueue -p)###显示已排队的所有传出邮件的列表###

6  postqueue -f###再次立即发送所有已排队的邮件###

 

 

接受邮件端:

1 vim /etc/postfix/main.cf

 

内容:

116 inet_interfaces = all                  ###25端口开启的网络接口。默认情况下,Postfix仅侦听来自本地主机的传入电子邮件。若要重新配置postfix以接收从远程主机发

送的本地邮件,必须设置inet_interfaces = all###

76 myhostname = qq-mail.westos.com         ###指定mta主机名称###

83 mydomain = qq.com   ###指定mta的域名###

99 myorigin = $mydomain                    ###指定邮件来源结尾(@后面的字符内容)

164 mydestination = $myhostname, $mydomain, localhost    ###接受邮件结尾字符的指定#

 

2 systemctl restart postfix.service

3 systemctl stop firewalld.service

4 mail###查看获得的邮件###

 

过程如下:

 

发邮件端:

 83 mydomain = westos.com###指定mta的域名###

99 myorigin = westos.com###指定邮件来源结尾(@后面的字符内容)

164 mydestination = $myhostname, $mydomain, localhost###接受邮件结尾字符的指定#

(二)dovecot配置

 

定义:

dovecot用来提供收件协议。

协议:端口:

pop3110

imap143

imaps993

pop3s995

给定用户名称,用户密码,dovecot程序带我们去看这个用户的邮件文件

 

配置

1 vim /etc/dovecot/dovecot.conf###谁能够访问并且通过验证###

内容:

 

24 protocols = imap pop3 lmtp###打开收件协议###

48 login_trusted_networks = 0.0.0.0/0###允许所有人连接###

49 disable_plaintext_auth = no###支持明文###

 

2 vim /etc/dovecot/conf.d/10-mail.conf###带用户去看什么文件###

内容:

 

30 mail_location = mbox:~/mail:INBOX=/var/mail/%u

 

3 mkdir /etc/skel/mail/.imap -p###在用户骨架文件里建立目录,则新建的用户均有该目录###

4 touch /etc/skel/mail/.imap/INBOX

5 mkdir /home/westos/mail/.imap -p###如果是原先就存在的用户,则要另外建该目录,因为用户骨架文件中没有该用户的这个目录###

6 touch /home/westos/mail/.imap/INBOX

 

过程如下:

[root@westos-mail ~]# yum install dovecot -y

[root@westos-mail ~]# systemctl start dovecot

[root@westos-mail ~]# netstat -anplte | grep dovecot
