[colug-432] Why does CentOS want to talk to mail.panamacityobgyn.com?

[Rob Stampfli]

Recently I loaded a VM with CentOS 6 (x86_64 6.7 final) from an old CD
image I happened to have laying around.  I noticed afterwards that the
VM had established a connection to 75.76.84.26:http, which translates
to mail.panamacityobgyn.com.  The connection is coming from the calendar
widget on the desktop.  Delete it and the connection goes away.  Hmm,
this didn't look kosher to me, so I pulled a copy of the latest CentOS
6.8 and loaded it instead.  This time the connection moved to 75.76.84.32
(static-75-76-84-32.knology.net).  (Actually, simply booting the install
disk is sufficient to observe this -- just bring up a shell on the desktop
and type "ss".  "lsof" will point to the actual culprit: "clock-app")

So what is going on here?  Why is this widget reaching out to these, well
at best unusual, IPs?

Enquiring minds...
