Or you can use
${if match{${run{/usr/local/bin/dig +short @... ...}}}{\N\.\N}}
On my VPS (obsolete FreeBSD 6) `dig` is in /usr/bin :
[root@lena ~]# exim -be '${if match{${run{/usr/bin/dig +short @8.8.8.8
1.0.0.127.cbl.abuseat.org}}}{\N\.\N}}'
[root@lena ~]# exim -be '${if match{${run{/usr/bin/dig +short @8.8.8.8
2.0.0.127.cbl.abuseat.org}}}{\N\.\N}}'
true
[root@lena ~]#
