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.

smtp_bind_address = 10.12.15.6
/etc/init.d/postfix restart
You can spread the IP, depending on the outgoing domain — goo.gl/eJ2rK - simeon_Fay commented on October 8th 19 at 01:58
Well, there is a patch, precisely how You have goo.gl/ekUFq — Postfix outgoing ip rotator - simeon_Fay commented on October 8th 19 at 02:01
1) Address will be the only one.
2)to scatter to the domains of customers is not easy.
3)Pay and price is not public. Want opensores and Donat. - Eulalia22 commented on October 8th 19 at 02:04
It seems to have to do on iptables. - Eulalia22 commented on October 8th 19 at 02:07
There are no other options, except that, for the crown, to reread the config of Postfix with a different address. - simeon_Fay commented on October 8th 19 at 02:10

Postfix is able beonsite such letters...
In my experience if you use SPF+DKIM, most public email servers remove the limitation on the number of emails from one domain/IP.
SPF and DKIM are bound to the DNS records which ultimately lead to ip addresses. And to register ALL IPS servers for domains is very frustrating when you can do domain-per-ip. - simeon_Fay commented on October 8th 19 at 02:00
spf doesn't exactly help as I tried it for some customers to configure.
dkim cabling is more difficult and not tried. - simeon_Fay commented on October 8th 19 at 02:03
Checked that neither dkim nor spf is not affected by the number of emails that can be sent to the postal service for some time, just tested for yahoo.com with whom customers have most of the problems.

Based on what your saying about the lifting of restrictions? spf quite a lot of mailers uses, mainly public services, as well as dkim. - Eulalia22 commented on October 8th 19 at 02:06
