i run the most recent postfix rpm from fedora core 2. I am getting some unusual warnings in my /var/log/maillog related to smtpd_peer_init: 219.91.118.152: hostname NK219-91-118-152.adsl. I googled this but only got one hit in spanish. Can someone please tell me what they think is happening?
The log looks like this like this:
# cat /var/log/maillog | grep 219.91.118.152
