I did.  In the linked message:

If you read that, you have a worked example of the various stanzas for
parts of Exim configuration.

If you need more than that, then I'm not the person to help you.  Paid
professional support from someone might help.

I apologizes but my exim knowledge is extremely limited, can you share an
example on how to setup two different users with that example.

Thanks so much and sorry for the hassle.

Yes.  This post might help:

  https://lists.exim.org/lurker/message/20171015.030553.5600347d.en.html

The two censored-for-web email addresses in the sample config extract
were `x...@gmail.com` and `z...@example.org`.

In essence: in the Router, use a lookup of `$sender_address` in some
data-source to get space-separated key=value pairs and stash that with
the `address_data` option, then refer to `$address_data` in the
Transport via `${extract{keyname}{$address_data}{true-val}{false-val}}`
to get the values of various options.

[exim] send mail based on origin domain

[Nicolas Leonel via Exim-users]

Hi guys,

Im using Sendgrid to send out email through my exim server, it uses a
remote SMTP host, port, username and password for sending email. The
problem is that now I would like to segment my delivery through multiple
SMTP users, aka SendGrid Sub-users.

It appears I can do this by either using their API or through the MTA which
I believe would be easier to implement, my question is does anyone know how
to specify a certain SMTP user and password depending on the domain used to
send the email from?

Below is the exim config involved for sending through SendGrid, let me know
if you want me to paste the entire config and I will do it right away.

Thanks in advance for all the help!

Section: AUTH

sendgrid_login:
driver = plaintext
public_name = LOGIN
client_send = :  username : password


Section: PREROUTERS

send_via_sendgrid:
driver = manualroute
domains = ! +local_domains
transport = sendgrid_smtp
route_list = "* smtp.sendgrid.net::587 byname"
host_find_failed = defer

Section: TRANSPORTSTART

sendgrid_smtp:
driver = smtp
hosts = smtp.sendgrid.net
hosts_require_auth = smtp.sendgrid.net
hosts_require_tls = smtp.sendgrid.net
