I've received these messages in two separate log files for quite some
time and I'd like to know how and where I need to go to rectify them?
I have aliases, host.conf, hosts.allow, hosts.deny, hosts.equiv in
/etc all setup to cover our network. I'm guessing, but could it be
coming from unresolved named or some other mail configurations files
(yes, newaliases was executed)?
