Either setup internal DNS or put entries for the ip's in /etc/hosts. Either way will remove that. You could also turn off sendmail's reverse lookup feature but be VERY careful there, if this mail server touches the internet i wouldnt do that. If its just internal mail or relaying to an external hub you could probably safely turn it off. --Larry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
