Topic: Throttling not working as expected

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.

Re: Throttling not working as expected

I am seeing identical behaviour on our server as what bijuedathodi reported.  We are also 0.8.3/1.8.1 LDAP on CENTOS 6.3

I would really like to get sender throttling working but get errors on all outbound mail with more than one recipient.

The following errors were occurring.  (IP's and names have been sanitized)  These are old errors that I archived so I could back and try to trouble shoot this at a later date.  (This is now that later date.)   Note the "invalid triplet" errors and the lack of "to=" log info from the message header.  There were just two recipients for this example.

We are also getting the invalid triplet error on inbound mail that we relay to another external mail server.  In this case mail for domain.com is relayed to exchange.domain.com.

Re: Throttling not working as expected

Maybe there's something wrong with Policyd setup in iRedMail. Currently, we run two Policyd instances, but it should work with just one instance, and listen on port 10031.

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

dovecot_destination_recipient_limit=1 is missing in postconf -n .but this entry is showing in main.cf file.
