How to teach postfix to send mails using multiple IPS
Very often somebody from the clients on the server sends the thousand letters, when most of them are in the same domain often comes it failed too many emails to send, well, a reference to the description of that try in an hour or send more slowly.
Of course you can set the sending times per second, but it will be no ice. Someone sent many emails, but will have to wait for everyone.
The server hangs 8 ip, I would like that Postfix when a large number of letters sent would be all using different ip.
Something in the standard documentation't find it.
