How to set up EXIM?

Question

Exim

There is a vesta panel / installed on maindomain.ru
5 domains have been created, each domain has its own ip for the user
klient1domen.ru / klient2domen.ru / klient3domen.ru / klient4domen.ru / klient5domen.ru
*** Letter helmet:
connect for example klient1domen. ru / [email protected]
look at the headers, we see:
Received-SPF: pass (mx277.i.mail.ru: domain of klient1domen.ru designates 00.0000.000 as permitted sender) client-ip=00.0000.000; [email protected]; helo= maindomain.ru ;
Received: from maindomain.com ([00.0000.000]:39768)
Why is the sender everywhere - helo / ip of the main server, the sender should be klient1domen.ru and its ip address, and maindomain.ru and its ip in recived, E
A small note !!! This is a relay, we connect to each domain individually correctly (I checked everything), but it gives out the MTA server everywhere and always

Answer 1

remote_smtp:
driver = smtp
helo_data = ${lookup{$sender_address_domain}\
nwildlsearch{EXIM_DIR/helo_data}{$value}{$primary_hostname}}
interface = ${lookup{$sender_address_domain}\
nwildlsearch{EXIM_DIR/outgoing_ip}{$value}{EXIM_OUTGOING_IP}}

helo_data and outgoing_ip will look like this:

domain.ru 1.1.1.1
domain2.ru 1.1.1.2

EXIM_DIR and EXIM_OUTGOING_IP must be set.
