Smart Host to Selected Domains

[tufancap]

Hello to everyone
There are many topics about this topic.
I read all topics
but a little difficult for novice or intermediate users like me
now I'll tell you what I want

I have 14 domains in cpanel
there are 3 e-commerce sites in them and they have heavy e-mail traffic.
I want to use a smart host for only 3 domains. I don't want to use it for all domains.
I think this is possible, but I did not understand it well.

1-
works with these settings
but for all domains

@[email protected] company_login: driver = plaintext public_name = LOGIN client_send = : MY-USERNAME : MY-PASS

@[email protected] send_via_company: driver = manualroute domains = ! +local_domains transport = company_smtp route_list = * company.mail.com

@[email protected] company_smtp: driver = smtp port = 25 hosts = company.mail.com hosts_require_auth = company.mail.com

2-
Turn off the smart host feature and
when you make these settings
send smart host from only one email address you added
but the email is waiting in a queue for a bit, but then it goes.
but you can send it from a single email address. I could not add a second or third email address.
other emails go normally. The email I added is sent via the smart host.

@[email protected] company_login: driver = plaintext public_name = LOGIN client_send = : MY-USERNAME : MY-PASS

@[email protected] send_via_company: driver = manualroute domains = ! +local_domains senders = [email protected] (that's the only difference) transport = company_smtp route_list = * company.mail.com

@[email protected] company_smtp: driver = smtp port = 25 hosts = company.mail.com hosts_require_auth = company.mail.com

How should I organize this scenario?
only the domains I want can send as smart hosts.
there are topics related to this in the forum but experienced user level information. I would appreciate it if you could help with a simpler expression.

Best regards

Hey there! I don't believe there is going to be an easier method than the things that have already been posted on the forum in the past. cPanel doesn't natively support this type of mail handling, so any work to get this configuration applied will involve advanced editing of the Exim configuration and router systems.

super,
wouldn't anyone write an example here?

 

[cPRex]

Since this isn't something that is included with the product by default, I don't have any official documentation. Were you able to search for other examples like this? Forward certain domain emails to Smart Host

 

[tufancap]

I have read all of these topics. There is no answer I'm looking for.



for example
here you can send emails from 1 domain with smart host.
I wish we could add domains with commas here.

Section: PREROUTERS send_via_dmail: driver = manualroute domains = ! +local_domains condition = "${if eq {$sender_address_domain}{mydomain.com}{true}{false}}" ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8 headers_add = "${perl{mailtrapheaders}}" transport = dmail_smtp route_list = * outbound.dmail.com {mydomain.com, domain2.com, domain3.} For example, is something like this possible? comma doesnt work, tried it. Is there a command that works?

 

[cPRex]

Unfortunately it isn't as simple as one command as there will need to be custom work performed to get that configured.

 

[tufancap]

well then.
Can anyone give other information about the subject I am looking for.

Solution
Specify only certain domains (of the sender email address) to send through the smarthost
Easy Settings
Replace the underlined text with your own settings

Exim Configuration Manager + Advanced editor

@[email protected] company_login: driver = plaintext public_name = LOGIN client_send = : MY-USERNAME : MY-PASS

@[email protected] send_via_company: driver = manualroute domains = ! +local_domains transport = company_smtp route_data = ${lookup{$sender_address_domain}lsearch*{/etc/exim/authorized_senders.txt}}

@[email protected] company_smtp: driver = smtp port = 25 hosts = company.mail.com hosts_require_auth = company.mail.com

create a file /etc/exim/authorized_senders.txt. Add domain names in below format into that file:

domain1.com: company.mail.com domain2.com: company.mail.com

Exim Restart

If you still don't understand, write it here. I will try to help.
