You are correct, resolve.conf does list my isp's dns 250.171.3.65 which is qwest. The internal windows workstations also point o the isp's dns server. Can I setup a cashing dns server on the mail server itself?? Absolutely. Assuming that none is running already: #> netstat -l | grep -e "domai

Rick, The reason i used top was because I noticed that mailscanner and smtpd were always on the list UNLESS the issue was occurring. I will try ps + grep next time as well. As for the ips they resolve quickly however they are all listed in /etc/hosts as we do not have an internal DNS. -jr [
