Hi,

I did the exim -h and got the following results:

hoof:/usr/exim/bin # ./exim -bh 196.26.82.66

**** SMTP testing session as if from host 196.26.82.66
**** Not for real!

>>> host in host_lookup? yes (*)
>>> looking up host name for 196.26.82.66
>>> IP address lookup failed
>>> host in host_reject? yes (failed to find host name or lookup

deferred)
LOG: connection from [196.26.82.66] refused (failed to find host name
from IP address)
554 SMTP service not available (failed to find host name from IP
address)


Also: It does not happen until I add the following line to the
configuration to block a problem spammer:

host_reject = 207.33.16.56 : 207.33.16.100 : *.mb00.net : *.topica.com

Regards

Nico
