Hide your exim version in the bannerLast Modified: Sep 10, 2019, 4:53 pm
By default, exim will show it's version in the smtp connection, eg:

220 jbmc-software.com ESMTP Exim 4.92.2 Tue, 10 Sep 2019 16:32:25 -0600

If you wish to hide this, you can do so with the smtp_banner option.
For exim.conf version 4.5.x+, to do this, you'd add code to the file:

/etc/exim.variables.conf.custom

Code:

smtp_banner="${primary_hostname} mail server"

and rebuild the /etc/exim.variables.conf with:

cd /usr/local/directadmin/custombuild
./build exim_conf
