I've got host:
catherine ~ # host catherine.espersunited.com
catherine.espersunited.com has address 70.234.122.251
catherine.espersunited.com mail is handled by 1
catherine.espersunited.com.
catherine ~ # mx catherine.espersunited.com
-bash: mx: command not found
But why would this affect catherine's ability to send mail within the
network? I'm mainly interested in stuff sent by cron. I even have an
alias in /etc/aliases that forwards all mail sent to root to
michael@???
