Directadmin uses include files in exim.conf to easily extend the config to enable a smart host. If you’re running exim.conf 4.5.7 or newer, you can use these 3 files for the related sections below:
wget -O /etc/exim.routers.pre.conf http://files.directadmin.com/services/SpamBlocker/smart_route/exim.routers.pre.conf wget -O /etc/exim.transports.pre.conf http://files.directadmin.com/services/SpamBlocker/smart_route/exim.transports.pre.conf wget -O /etc/exim.authenticators.post.conf http://files.directadmin.com/services/SpamBlocker/smart_route/exim.authenticators.post.conf
Step 1:
First edit /etc/exim.authenticators.post.conf
change the section ”’hide client_send = : [email protected] : yourpass”’
Be sure to keep the = and : sections. Change [email protected] to your mailbaby username. Change yourpass to your mailbaby pass. For example
hide client_send = : mailbaby : 68e9af2444722ffd228497dec28b0ae3b5c6413f7a2a9455c410872770165a66
Your mailbaby username will not contain a @domain.com, but be a single username.
Step 2:
Edit /etc/exim.transports.pre.conf
Change ”’X-Authenticated-Id”’ to ”’X-AuthUser”’
With this change the section:
headers_add = "${if def:authenticated_id{X-Authenticated-Id: ${authenticated_id}}}"
Becomes:
headers_add = "${if def:authenticated_id{X-AuthUser: ${authenticated_id}}}"
Step 3:
Edit exim.routers.pre.conf
Change ”’route_list = * smtp.yourisp.com”’
Important: keep the * and there is a space after it
Change smtp.yourisp.com to relay.mailbaby.net
Step 4:
Restart exim based on your operating system
centos7/8/ubuntu would use
systemctl restart exim.service
Step 5: Set default SPF
/usr/local/directadmin/directadmin set extra_spf_value ” relay.mailbaby.net”
systemctl restart directadmin.service
