I'm trying to use postfix + policyd2 to limit amount of outgoing emails. But when implementing policyd2 policies i get Access denied - no mater what i do i get denied.
- Postfix version 2.11.4
- PolicyD2 (cluebringer) version 2.0.14-1
Error box from email client:
An error occurred while sending mail. The mail server responded: 4.7.1 <[email protected]>: Recipient address rejected: Access denied. Please check the message recipient [email protected] and try again.
When i turn off policyd2 in postfix /etc/postfix/main.cf
everything works:
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,
If i turn it back on, this is what i get /var/log/maillog
:

Policy example.
Create policy:
INSERT INTO policies VALUES (1, 'In Out', 10, 'In Out Policy', 0);
INSERT INTO policy_members VALUES (1, 1, 'any', 'any', '' ,0);
Add quotas - actions:
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.');
Add quota limits:
INSERT INTO quotas_limits (QuotasID, Type, CounterLimit) VALUES (1,'MessageCount', 12);
INSERT INTO quotas_limits (QuotasID, Type, CounterLimit) VALUES (2,'MessageCount', 20);
Can't use web gui (no PHP) - so I'm not sure if it is correct. Was searching and trying different policy examples but the error remains exactly the same.
Permissions on policyd2 sqlite3 database file were wrong.
PolicyD2 has capability to run daemon as specific user, in my case:
Permissions on the database were root:root.
After changing to policyd:policyd i could send emails.
Now Acces denied error make sense.
