Route all outgoing emails to another cPanel server

[MaRiOsGR66]

I have a cpanel server of which's ip is blocked currently by yahoo,
and another cpanel server which's ip is clear,
I would like to do the modifications needed in exim to route all outgoing email to the 2nd cpanel server (just like you do it with Sendgrid)
but I don't know how.

Any help?

I did try it and immediately I was getting the error:

Please add following in your exim configuration

smarthost_dkim:
driver = manualroute
domains = !"+local_domains +smart_hosts"
condition = "${if eq{${lookup{$sender_address_domain}partial-lsearch{/etc/staticroutes}{$value}}}{}{false}{true}}"
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
headers_add = "${perl{mailtrapheaders}}"
require_files = "+/var/cpanel/domain_keys/private/${sender_address_domain}"
transport = remote_smtp_smart_dkim
route_list = !+local_domains "${lookup{$sender_address_domain}partial-lsearch{/etc/staticroutes}}"

smarthost_regular:
driver = manualroute
domains = !"+local_domains +smart_hosts"
condition = "${if eq{${lookup{$sender_address_domain}partial-lsearch{/etc/staticroutes}{$value}}}{}{false}{true}}"
ignore_target_hosts = 0.0.0.0 : 127.0.0.0/8
headers_add = "${perl{mailtrapheaders}}"
transport = remote_smtp_smart_regular
route_list = !+local_domains "${lookup{$sender_address_domain}partial-lsearch{/etc/staticroutes}}"

#TRANSPORTSTART
sendbysmarthoststransport:

port = ${extract{port}{${lookup{$sender_address_domain}lsearch{/etc/exim_smarthosts}}}}
hosts_require_auth = $host_address

remote_smtp_smart_dkim:

helo_data = ${if exists {/etc/mailhelo}{${lookup{$sender_address_domain}lsearch*{/etc/mailhelo}{$value}{$primary_hostname}}}{$primary_hostname}}

If you still having issue then please share your exim configuration

 

[dalem]

had a typo in
smarthost_transport:

corrected in post above to fix "smarthost_transport" not found"

tested on one of my own servers & works

Updated
Added DKIM to Section: TRANSPORTSTART to pass dkim
Dont forget to add SPF

Note: we use this config on Our servers it works without issue
Note: you may need to tweak your settings

Note: had to modify Section: TRANSPORTSTART to pass dkim our mail server is stand alone ( no cpanel) & the dkim is passed from there so insure that it passess it correctly make mods as necesssary
