我正在尝试使用 postfix + policyd2 来限制发送的电子邮件数量。但是在实施 policyd2 策略时,我被拒绝访问 - 无论我做什么,我都会被拒绝。
- Postfix 版本 2.11.4
- PolicyD2(cluebringer)版本 2.0.14-1
电子邮件客户端的错误框:
发送邮件时出错。邮件服务器响应:4.7.1 <[电子邮件保护]>:收件人地址被拒绝:拒绝访问。请检查邮件收件人[电子邮件保护]然后再试一次。
当我关闭 postfix 中的 policyd2 时,/etc/postfix/main.cf
一切正常:
smtpd_end_of_data_restrictions=check_policy_service inet:127.0.0.1:10031
smtpd_recipient_restrictions=check_policy_service inet:127.0.0.1:10031,
如果我重新打开它,我得到的是/var/log/maillog
:

政策示例。
创建策略:
INSERT INTO policies VALUES (1, 'In Out', 10, 'In Out Policy', 0);
INSERT INTO policy_members VALUES (1, 1, 'any', 'any', '' ,0);
添加配额-操作:
INSERT INTO quotas (PolicyID,Name,Track,Period,Verdict,Data) VALUES (1,'Sender:user@domain', 'Sender:user@domain', 60, 'DEFER', 'Deferring: To many messages from sender in last 60s.');
INSERT INTO quotas (PolicyID,Name,Track,Period,Verdict,Data) VALUES (1,'Recipient:@domain', 'Recipient:@domain', 60, 'REJECT', 'Quota limit reached.');
添加配额限制:
INSERT INTO quotas_limits (QuotasID, Type, CounterLimit) VALUES (1,'MessageCount', 12);
INSERT INTO quotas_limits (QuotasID, Type, CounterLimit) VALUES (2,'MessageCount', 20);
无法使用 Web GUI(没有 PHP)——所以我不确定它是否正确。搜索并尝试了不同的策略示例,但错误仍然完全相同。
答案1
policyd2 sqlite3 数据库文件的权限错误。
PolicyD2 能够以特定用户身份运行守护程序,就我的情况而言:
/etc/policyd.conf
# User to run this daemon as
user=policyd
group=policyd
数据库的权限是 root:root。
-rw-r--r-- root root policyd2.db
更改为 policyd:policyd 后,我就可以发送电子邮件了。
-rw-r--r-- policyd policyd policyd2.db
现在访问被拒绝错误是有意义的。
