I've had a Linux box running here for years. It is pointed to by first.second.net and first1.second.net as rented from no-ip, and there's a script to tell no-ip what the outside IP address is for my router. My router is set to forward a few ports to this computer. It was mostly setup for testing the development of PHP scripts. I needed to also add a git service on it for some outside collaboration. I initially attempted to use GitLab-CE. I found that to be difficult. I ended up installing a lighter-weight solution called Gogs. I obtained a 3rd name from no-ip, and called it third.second.net Gogs required I install a mail program. I was unsuccessful in getting PostFix to install, but succeded with sendmail.
Everything seems to be working well, except there is a lot of activity being logged. One particular item is that /var/log/mail.log is filling up with the same repition error message:
May 25 03:00:01 SERVER2 sm-msp-queue[2899]: My unqualified host name (SERVER2) unknown; sleeping for retry
May 25 03:01:01 SERVER2 sm-msp-queue[2899]: unable to qualify my own domain name (SERVER2) -- using short name
May 25 03:20:01 SERVER2 sm-msp-queue[2997]: My unqualified host name (SERVER2) unknown; sleeping for retry
May 25 03:21:01 SERVER2 sm-msp-queue[2997]: unable to qualify my own domain name (SERVER2) -- using short name
May 25 03:40:01 SERVER2 sm-msp-queue[3092]: My unqualified host name (SERVER2) unknown; sleeping for retry
May 25 03:41:01 SERVER2 sm-msp-queue[3092]: unable to qualify my own domain name (SERVER2) -- using short name
So I am wondering, do I need to change my SERVER2 designation someone to some FQDN? And what would I use for that FQDN, since I have 3 pointing to the system, and none of them have 'SERVER2' as a part of the name? I think that having 2 errors every 20 minutes in the log is kinda excessive.
My Linux distribution is Kubuntu 18.04.04 LTS desktop.
