Hi,
Shodan [1] reports loads of vulnerable [2] servers running pre 4.92
versions of Exim, those include Debian Exim variants reporting 4.89
.... even for fully patched servers.
$ telnet mail.example.org 25

# dpkg-query -l|grep \ exim|awk '{print $2,$3}'|column -t

exim4-config 4.89-2+deb9u4
exim4-daemon-heavy 4.89-2+deb9u4
exim4-doc-html 4.89-1
Is there a way to provide version of "4.92" easily or some other text
to stop the likelihood of outsiders trying to pound on and exploit the
server? Even though they won't be able to do successfully due to up to
date patch status.
