Thank you for your reply. I'm not getting lucky in this point. What I did
was:
host_reject = 1.2.3.4 : 5.6.7.8
then restart exim. but when I did "exim -bh 1.2.3.4", it return me like
this:
**** SMTP testing session as if from host 1.2.3.4
**** Not for real!
>>> host in host_lookup? yes(*)
>>> looking up host name for 1.2.3.4
>>> IP address lookup failed
>>> host in host_reject? no (option unset)
>>> host in host_reject_recipients? no (option unset)
>>> host in rbl_hosts yes(*)
>>> checking RBL domain blackholes.mail-abuse.org failed
>>> => that means it's not black listed at blackholes.mail-abuse.org ...
Can you see anything wrong in this message? How can I fix it?
Thanks again
