Hi,
look at this:
# grep host_reject /etc/exim.conf
host_reject_recipients = +allow_unknown:/etc/exim/blacklist
# grep 195.65.227.21 /etc/exim/blacklist
195.65.227.21
# exim -bh 195.65.227.21
**** SMTP testing session as if from host 195.65.227.21
**** Not for real!
>>> host in host_lookup? yes (0.0.0.0/0)
>>> looking up host name for 195.65.227.21
>>> IP address lookup failed
>>> host in host_reject? no (option unset)
I don't quite understand why this fails.
Ciao,
Martin
