Hi
I have implemented Quota status to postfix in our setup. I have an imap server (dovecot) and mail server (postfix) in every node. I am able to send quota status to postfix and mails are rejected after 100% mail quota is crossed. This rejection is happening both in across the nodes and within the nodes.
The problem is if I am sending mails to any node and if any other node's dovecot is down, mails are not going. For example, I am sending an email within the system but if some other node's dovecot is down then email within the system also will not go.
My dovecot version is 2.2.10. My postfix version is 2.1.10.
*doveconf -n output is below:-*
# 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-514.el7.x86_64 x86_64 Red Hat Enterprise Linux Server release 7.3 (Maipo) xfs auth_debug = yes base_dir = /var/run/dovecot/ first_valid_gid = 5000 first_valid_uid = 5000 hostname = CmdHQ login_greeting = ^^^^^^^^^^Dovecot ready^^^^^^^^^^ mail_debug = yes mail_gid = 6000 mail_location = Maildir:/var/mail/vmail/tcs.mil.in/%n mail_plugins = " quota" mail_uid = 6000 mbox_write_locks = fcntl passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } plugin { quota = maildir:User quota quota_rule = *:storage=8KB quota_rule2 = *:messages=12B quota_status_nouser = DUNNO quota_status_overquota = 552 5.2.2 Mailbox is over quota / mailbox is full quota_status_success = DUNNO quota_warning = storage=80%% quota-warning 80 %u } postmaster_address = postmaster@tcs.mil.in service auth { unix_listener auth-userdb { mode = 0600 user = postfix } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service quota-status { client_limit = 1 executable = quota-status -p postfix inet_listener { port = 54317 } } service quota-warning { executable = script /usr/local/bin/quota-warning.sh unix_listener quota-warning { group = postfix mode = 0666 user = postfix } user = postfix } ssl = required ssl_ca =
Here "service quota status" is the concerned section in conf file.
*Postfix configuration is below:- *
smtpd_relay_restrictions = check_policy_service inet:201.123.80.9:54317 check_policy_service inet:201.123.80.23:54317
virtual_transport=lmtp:unix:private/dovecot-lmtp
Here, I am querying both two nodes. 201.123.80.9 is the other node. 201.123.80.23 is the node within which, email is sent.

I am understanding what the logs are trying to say. But I am not able to resolve the issue even after searching solution on internet and trying different hit and trials by myself. I want that if i am sending email to any node or within node, the configuration relating to "check _policy_service" for other node does not interfere and mail goes properly. At the same time I can also fetch quota status from other nodes.
If I can get any help regarding this it will be really appreciable as I have tried a lot of options already.
