24 protocols = imap pop3 lmtp ##支持收件协议
48 login_trusted_networks = 0.0.0.0/0 ##信任网络
49 disable_plaintext_auth = no ##开启明文认证
vim /etc/dovecot/conf.d/10-auth.conf
123 !include auth-sql.conf.ext ##开启mysql的认证方式
3.生成dovecot读取mysql的配置
cp /usr/share/doc/dovecot-2.2.10/example-config/dovecot-sql.conf.ext /etc/dovecot/dovecot-sql.conf.ext
vim /etc/dovecot/dovecot-sql.conf.ext
32 driver = mysql ##数据库类型
71 connect = host=localhost dbname=email user=postuser password=postuser ##查询时用到的库、用户、密码
78 default_pass_scheme = PLAIN ##默认认证方式为明文
107 password_query = \ ##查询密码匹配
108 SELECT username, domain, password \
109 FROM users WHERE username = '%u' AND domain = '%d'
30 mail_location = maildir:/home/vmail/%d/%n ##指定邮件位置
168 first_valid_uid = 666 ##邮件文件查询用户的身份
[[email protected] ~]# telnet 172.25.254.143 110
Trying 172.25.254.143...
Connected to 172.25.254.143.
Escape character is '^]'.
2.[[email protected] ~]# vim /etc/postfix/main.cf
myhostname = null-mail.example.com
mydomain = example.com
myorigin = westos.com
inet_interfaces = all
mydestination =
relayhost = 172.25.254.143
1.软件的插件安装
yum install dovecot dovecot-mysql -y
2.编辑配置文件
24 protocols = imap pop3 lmtp ##支持收件协议
48 login_trusted_networks = 0.0.0.0/0 ##信任网络
49 disable_plaintext_auth = no ##开启明文认证
vim /etc/dovecot/conf.d/10-auth.conf
123 !include auth-sql.conf.ext ##开启mysql的认证方式
3.生成dovecot读取mysql的配置
cp /usr/share/doc/dovecot-2.2.10/example-config/dovecot-sql.conf.ext /etc/dovecot/dovecot-sql.conf.ext
vim /etc/dovecot/dovecot-sql.conf.ext
32 driver = mysql ##数据库类型
71 connect = host=localhost dbname=email user=postuser password=postuser ##查询时用到的库、用户、密码
78 default_pass_scheme = PLAIN ##默认认证方式为明文
107 password_query = \ ##查询密码匹配
108 SELECT username, domain, password \
109 FROM users WHERE username = '%u' AND domain = '%d'
125 user_query = SELECT maildir, 666 AS uid, 666 AS gid FROM emailuser WHERE userid = '%u'
30 mail_location = maildir:/home/vmail/%d/%n ##指定邮件位置
168 first_valid_uid = 666 ##邮件文件查询用户的身份
175 first_valid_gid = 666
systemctl restart dovecot
4.测试：[[email protected] ~]# telnet 172.25.254.143 110
Trying 172.25.254.143...
Connected to 172.25.254.143.
Escape character is '^]'.
+OK [XCLIENT] Dovecot ready.
