Hello there, Sometimes we need send volume mails to our customers before holiday, most of their mail address is hotmail, I've slowed down its sending rate by setting smtp_destination_rate_dealy = 15s , but I still get rejected info from hotmail. I don't know why.
Is there any way for postfix s to stop sending mail to hotmail while the rejected info reached, then I let my process sleep for a while and retry again sometime later? Should I recode postfix ? Thanks, Tony.
