SSP rate limit exceeded
When I am a sending newsletter I got the following error . Please find the error
cannot send the message . the server responded:452 xxx.xxx.xx.xx Has exceeded SSP rate limit.
where xxx.xxx.xx.xx is sender ip address.
In that server I am using centos 6.5 and postfix SMTP
I am using port number 25 is working properly if the mails sending limit is high i.e 600/hour then I got that error on port number 25 then I changed to port 587 then its working fine.
Is there any restriction sending mails limit from my ISP or from your end.
