I haven't read through all of this, but is this a CentOS 7 machine? If so
.. I
believe that systemd has some name resolution facility in it. Has that
been
looked into?

That should be it. Putting dns first works if you can guarentee
that
DNS works fine all the time but if your DNS caches that localhost doesn't exist then /etc/hosts isn't used.
aliases: files nisplus
since you are doing email
aliases: files

Hello,
Made those changes and rebooted. No change. Still times out.
OK in that case something is really taking your system for a ride. I would check to see if that 71.28.79.87 is your 'public' ip address with
curl -4 icanhazip.com
if it is then something from named or some other utility is translating localhost for you. host -v localhost might give you more information on what is giving lookups crazy answers

Thanks, yes it's a CentOS 7.5.1804. I do not know about the system.
