i Am using iRedAdmin-Pro    v1.8.1 (LDAP)+CentOs 6
what i want to acheive is only enabling sender throttling, recipient throttling not needed
Throttling setting via controll panel  is not working as expected i followed the wiki guide.I have made the changes as per the guide .My settings follows
/etc/policyd.conf
SENDERTHROTTLE=0
SENDER_THROTTLE_SASL=0
SENDER_THROTTLE_HOST=1
RECIPIENTTHROTTLE=0
File: /etc/policyd_sender_throttle.conf
SENDERTHROTTLE=1
SENDER_THROTTLE_SASL=1
SENDER_THROTTLE_HOST=0
RECIPIENTTHROTTLE=1
When ever i am sending mails to multiple email ids i am getting  "smtp Server policy Rejection Error".If iam seng to single email id ,it works.
By changing back to RECIPIENTTHROTTLE=0 in /etc/policyd_sender_throttle.conf,Error goes and everything works.But throttling is not working.
For Example
i enabled sender throttling in a domain through control panel after making the above changes and set maximum out going messages per day to 2 for that domain.Even after limiting i can send multiple mails from a user of this domain.

Error SMTP: [450] 4.7.1 <END-OF-MESSAGE>: End-of-data rejected: Policy Rejection- Invalid data

dovecot_destination_recipient_limit=1 is missing in postconf -n .but this entry is showing in main.cf file.
Error found while sending from roundcube
