Postfix 内部邮件管理

邮件组限定修改手顺

1）在main.cf里定义如下的smtpd_restriction_classes：引用:
# restrictions--mail police
smtpd_restriction_classes = local_out_only local_in_only
local_out_only = check_recipient_access hash:/etc/postfix/local_domains, reject
local_in_only = check_sender_access hash:/etc/postfix/local_domains, reject

2）将main.cf里的smtpd_recipient_restrctions定义为：引用:
smtpd_recipient_restrictions =
  check_sender_access hash:/etc/postfix/local_out_senders
  check_recipient_access hash:/etc/postfix/local_in_senders
  permit_mynetworks,
  permit_sasl_authenticated,
  reject_non_fqdn_hostname,
  reject_non_fqdn_sender,
  reject_non_fqdn_recipient,
  reject_unauth_destination,
  reject_unauth_pipelining,
  reject_invalid_hostname
  check_policy_service inet:127.0.0.1:10030

3）编辑/etc/postfix/local_in_senders：引用（每一行为一个邮件组）:
  local_in_only
  local_in_only

4）编辑/etc/postifx/local_out_senders：引用:
目前对于出去的组还没有限定，故为空！！此选项的意思是在oxoxoox邮件组里面有非oxoxoox.com.cn的邮箱

时，比如有oxoxoox.com的邮箱，如果做了限定将会无法收到。

5）编辑/etc/postfix/local_domains：引用:
oxoxoox.com.cn OK
oxoxoox.com OK

6）为3，4，5建立对应的hash文件： 引用:

# postmap hash:/etc/postfix/local_in_senders
# postmap hash:/etc/postfix/local_out_senders
# postmap hash:/etc/postfix/local_domains
