Apart from the MX dynamic information, is there a way within Postfix to specify that specific rate limiting toward that specific hostname/ip address ? My use-case is I have a bunch of domains all of them using the same hostname/IP as MX and they could increase in the number but still having the same MX... so to me it would be acceptable to address just that specific MX sending. I thought about the iptables solution, but I was searching a Postfix-only solution. Thank you again Marco
