Thanks Yeah, i know it does not depend on the MTA. I use multiple IPs with SPF, DKIM and DMARC.
Regularly update the lists, used transport to limit yahoo sending but no success. The problem i see that even though set a delay to send to yahoo, the emails which are there in deferred queue tend to flush really quick and the IP gets grey listed again. Anything you suggest to control the sending speed and the retry interval at which deferred queue gets flushed out. Can we control the amount of emails which gets from deferred queue to active queue. -- Sent from: http://postfix.1071664.n5.nabble.com/Postfix-Users-f2.html
