postfix+mysql

1.配置mysql

实验之前，制作要使用数据库和表

添加数据库用户，并给其授权

* vim /etc/postfix/mailuser.cf ##查询用户名

1 host = localhost ##数据库主机

2 user = postuser ##登录数据库用户

3 password = 123 ##登录密码

4 dbname = email ##postfix查询库的名称

5 table = emailuser ##postfix查询表的名称

6 select_field = username ##postfix查询的字段

7 where_field = username ##给postfix查询的条件

* vim /etc/postfix/maildomain.cf ##域名查询

1 host = localhost

2 user = postuser

3 password = 123

4 dbname = email

5 table = emailuser

6 select_field = domain

7 where_field = domain

vim /etc/postfix/mailbox.cf

1 host = localhost

2 user = postuser

3 password = 123

4 dbname = email

5 table = emailuser

6 select_field = maildir

7 where_field = username

测试

2.配置postfix

groupadd -g 666 vmail ##添加用户组并指定gid为666

useradd -s /sbin/nologin -u 666 vmail -g 666 ##添加用户，并指定uid和gid为666

* postconf -e "virtual_mailbox_base = /home/vmail" ##设定虚拟用户邮件目录

postconf -e "virtual_uid_maps = static:666" ##指定虚拟用户建立文件uid

postconf -e "virtual_gid_maps = static:666" ##指定虚拟用户建立文件gid

postconf -e "virtual_alias_maps = mysql:/etc/postfix/mailuser.cf" ##指定MySQL查找主机

postconf -e "virtual_mailbox_domains = mysql:/etc/postfix/maildomain.cf" ##指定MySQL查找域名

postconf -e "virtual_mailbox_maps = mysql:/etc/postfix/mailbox.cf" ##指定MySQL查找邮箱

*systemctl restart postfix ##重启postfix服务

测试
