maybe you try this in main.cf:

smtpd_client_message_rate_limit = 10

The maximum number of message delivery requests that an SMTP client may make in the time interval

Hi All

Can some body help me to configure my Postfix server.
What i am really looking for is mail flow control..
I have postfix server configured internaly which is open relay.

since it is open realy server facing a probelm due to huge mail flood from application server.

So i want to controll the mail flow rate based on sending host/client in postfix.

For ex.
host 192.168.1.2 is sending too many mails

i want control /slow down the mail flow from ths host only based on time/no of connection

Can anybody help me on this ?

Another good way is to block outgoing spam is to check the amount of sent emails per user which get bounced. Normally this happens not more than 10 times per hour. When this amount grows it’s time to check the sender.
