Who has practical experience in organizing bulk emails from their servers?

Question

PHP

We are raising an email mailing server, we need a specialist in this topic with practical experience in order to advise and help in development.

Who faced and how did you manage to solve the problem of mailing to large subscriber bases (from 2,000,000 and more email addresses)?

Answer 1

oh, run ... They don't like "mailers" here.

Answer 2

Guys, but seriously?
SPAM has nothing to do with it. A number of organizations we work with have tens of thousands of clients and hundreds of thousands of subscribers.
How to send letters to them?
PS: Is it really only the creators of small projects on Habré?

Answer 3

Well, we are setting up dkim, spf.
If there is a lot of helmet, we hang a lot of ip from different subnets on the server and rotate when sending. Most email servers have a limit of no more than a thousand letters from one IP per hour, Google, Yahoo and Yandex have this.
We put the queue of letters in memory if we are not afraid to lose them, or on ssd if we are afraid.
You can try to use ssmtpd, it is very simple and works much faster than any sendmyl, postfix and ekzimov.
There are also tricks of a political nature, but they already require agreements with the main email services.

Answer 4

We are looking for the words dkim, spf, ptr
