Client Mail Server

     The client e-mail server,, which provides imap, pop3, and smtp for clients and for webmail, stopped talking to the network sometime last night.

     It has been rebooted and is now operational again.

     I do not know what is causing it to do this but it is an old centos6 machine that I am in the process of configuring a new server based upon ubuntu 17.04 and the latest versions of all the software to replace the centos6 machine.

     Centos6 does not get maintained well by RedHat which is why I moved the incoming servers to ubuntu17.04.  Configuring this server takes longer because there are more software systems involved but I am getting close.
