Hello i'd like to know if there is a guide to set up a server to send many email ao hour, such as 100.000 email per hour.
I try to set up a server with pmta (i try to send 100.000 email hour) but the open rate is very very low (1%), i set up the same server with postfix (max 20.000 email per hour) and the open rate is very good (15%).
I'd like to know if there is a guide to set up a server with many postfix instance and ip rotation or witch is the best way to create a very strong email server.
