Direct Admin

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
