postfix限制部分用戶發送和接收外部郵件
1) 編輯main.cf,在最後添加
smtpd_restriction_classes = local_only, local_only1
local_only = check_recipient_access hash:/etc/postfix/local_domains,reject
local_only1 = check_sender_access hash:/etc/postfix/local_domains,reject
smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/local_senders,
check_recipient_access hash:/etc/postfix/local_recipients,
permit_mynetworks,
permit_sasl_authenticated,
reject_non_fqdn_hostname,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
reject_unauth_destination,
reject_unauth_pipelining,
reject_rhsbl_sender,
reject_unknown_sender_domain,
reject_invalid_hostname
注:從第5行開始前面空一格.
2) 新增local-domains , local_senders , local_recipients
local_domains:
domain.com OK
192.168.0.1 OK
local_senders:
kently@domain.com local_only
local_recipients:
kently@domain.com local_only1
3) postmap hash:/etc/postfix/local_domains
postmap hash:/etc/postfix/local_senders
postmap hash:/etc/postfix/local_recipients
4) postfix reload
1 在main.cf里定义如下的smtpd_restriction_classes：
# restrictions
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：
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,
3）编辑/etc/postfix/local_in_senders：
aa@aa.com local_in_only
bb@bb.com local_in_only
4）编辑/etc/postifx/local_out_senders：
aa@aa.com local_out_only
bb@bb.com local_out_only
5）编辑/etc/postfix/local_domains：
aa.com OK
bb.com OK
6）为3，4，5建立对应的hash文件：
# postmap hash:/etc/postfix/local_in_senders
# postmap hash:/etc/postfix/local_out_senders
# postmap hash:/etc/postfix/local_domains
修改完成后老报错.错误如下:
telnet 25端口后可以连上。但是什么都不显示
日志如下.
