postfix 只允许指定的用户给特定的..

公司需求：只有公司高层才可以向全体员工发送邮件，除此之外，均无权向全体员工发送邮件。

公司高层邮箱：

[email protected]

全体员工邮箱：[email protected]

解决方法如下：

1，修改配置文件（注：红色的代表新增加的）

[root@mail postfix]# vi main.cf

#youshengtao 2010-10-12

smtpd_restriction_classes = local_only, local_only1

local_only = check_recipient_access hash:/etc/postfix/plugin/plugin.list,reject

local_only1 = check_sender_access hash:/etc/postfix/plugin/plugin.users,reject

smtpd_recipient_restrictions = reject_unknown_sender_domain, reject_unknown_recipient_domain, reject_non_fqdn_sender, reject_non_fqd

n_recipient, reject_unlisted_recipient, check_sender_access hash:/etc/postfix/plugin/plugin.users, check_sender_access hash:/etc/postfix/plugin/local_senders, check_recipient_access hash:/etc/postfix/plugin/local_recipients, permit_mynetworks, permit_sasl_authenticated, rejec

t_unauth_destination, reject_non_fqdn_helo_hostname, reject_invalid_helo_hostname, check_policy_service inet:127.0.0.1:10031

2，建立相关的目录，也可以不建目录，直接放在postifx目录下面，不过，为了以后维护方便，我还是建了一个目录。

[root@mail ~]# mkdir -p /etc/postfix/plugin

[root@mail ~]# cd /etc/postfix/plugin/

[root@mail plugin]# vi local_recipients

[email protected] local_only1

[root@mail plugin]# vi local_senders

[email protected] local_only

[root@mail plugin]# vi plugin.list

[email protected] OK

[root@mail npc]# vi plugin.users

[email protected] OK
