使用 postfix 限制发件人和收件人

  • 772

对不起，关于这个话题的问题加倍了，但是有很多，有些非常令人困惑，有些仍然是“旧”格式，有些与我的情况不匹配。

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)

还有“[email protected]”

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]

我想要实现的是该电子邮件服务器（[email protected]）的只有 1 个用户能够发送和接收电子邮件，任何其他用户几乎必须立即被拒绝。而这个用户只能接收来自少数用户和“recipient_domains”的邮件

受限发件人：

[email protected] allowed

收件人域：

[email protected] allowed
[email protected] allowed
thisserveronly.net allowed

如果我的配置有错误或者我错过了什么，请任何人提供建议？

    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 中的帐户发送到thisserver.net，“rcpt to:”将只发送到“recipient_domain”，里面只有[email protected]。

    当然，我还为 SPF 添加了 dns 上的 TXT 记录。
