对不起，有关这个话题的问题翻倍，但有这么多，有些是非常混乱，有些仍然是“旧”的格式，其他一些不符合我的情况。
smtpd_restriction_classes = allowed allowed = permit smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/restricted_senders, reject smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, permit_sasl_authenticated, check_recipient_access hash:/etc/postfix/recipient_domains, reject_rbl_client zen.spamhaus.org, reject_rhsbl_helo dbl.spamhaus.org, reject_rhsbl_sender dbl.spamhaus.org 我有这个代码工作，但我仍然可以发送邮件到[email protected]（一些随机用户）
Apr 4 13:40:46 mail-server postfix/local[22937]: 0C1C5160030: to=<[email protected]>, relay=local, delay=0.23, delays=0.23/0/0/0, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail)
Apr 4 13:41:42 mail-server postfix/smtpd[22931]: NOQUEUE: reject: RCPT from mail-vk0-f52.google.com[209.85.213.52]: 550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<mail-vk0-f52.google.com> Apr 4 13:41:42 mail-server postfix/smtpd[22931]: disconnect from mail-vk0-f52.google.com[209.85.213.52]
我想实现的是，这个电子邮件服务器（[email protected]）只有一个用户能够发送和接收电子邮件，其他任何一个都必须立即被拒绝。 而这个用户只能接收一些用户的邮件和“recipient_domains”
restricted_senders：
[email protected] allowed
recipient_domains：
[email protected] allowed [email protected] allowed thisserveronly.net allowed
如果我的configuration有错误或者我错过了什么，请问任何人都可以build议吗？
我想我解决了：
smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sender_restrictions = check_sender_access hash:/etc/postfix/restricted_senders, reject smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_recipient_access hash:/etc/postfix/recipient_domains
允许我从restricted_senders帐户发送到thisserver.net，“rcpt to：”只发送给“recipient_domain”，里面只有[email protected]。
当然，我也在SPF的dns上添加了TXTlogging。
