Hi Zhang,

We need to restrict certains users not to send mail to particular domains. We have installed iRedapd and trying to restrcit by adding in whitelist/blacklist  features in ProLDAP 1.6.3 admin panel. But the mails sent to that domain are getting delivered, not getting quarantined or rejected.

Thanks,

# postconf smtpd_end_of_data_restrictions

2) Please show me whole content of file /opt/iredapd/etc/iredapd.ini? Please REMOVE password before posting.
3) Click 'Export account to LDIF' in your user's profile page (under tab "General"), then paste whole LDIF data here. (REMOVE password and other sensitive information before posting)

Re: whitelist/ Blaclist

Postfix and iRedAPD config looks fine.

As LDIF data shows, you want to block emails sent TO gmail.com, could you please turn on debug mode in iRedAPD with below setting in both iredapd.ini and iredapd-rr.ini, then send a test email and paste iRedAPD log here to help troubleshoot?

# Log level: info, error, debug.
log_level       = debug

Please post another log file with debug log.

You have permit_sasl_authenticated in front of "check_policy_service inet:127.0.0.1:7778", that's why it doesn't work at all.

The correct setting is:

smtpd_sender_restrictions = check_policy_service inet:127.0.0.1:7778, permit_mynetworks, reject_sender_login_mismatch, permit_sasl_authenticated

Re: whitelist/ Blaclist

Hi Zhang,

Thanks for providing the solution.

We have now set
smtpd_sender_restrictions = check_policy_service inet:127.0.0.1:7778, permit_mynetworks, reject_sender_login_mismatch, permit_sasl_authenticated  and in /opt/iredapd/etc/iredapd.ini file changed the order of plugins as below
plugins = block_amavisd_blacklisted_senders, ldap_recipient_restrictions, ldap_maillist_access_policy
previously it was like
plugins =  ldap_maillist_access_policy, block_amavisd_blacklisted_senders, ldap_recipient_restrictions

and in iredapd-rr.ini in general tab "bypass_mynetworks = no" line was not there added that line

Now we are able to restrict sending mails to specific domains from specific users.

Thanks,
Regards,
Mohan
