Any reason why Virtualmin created three new servers with a series of numbers, but they are not real servers - if that makes sense. They are listed in the servers, but no details
Hmm, which Virtualmin version is it that you have there?

This was a bug in an older version of Virtualmin, those “phantom servers” were created when backups that only included Virtualmin config but no domains were taken.
Using Virtualmin GPL 1.675
Seems that the fake servers have mail turned on but nothing else. They do no show up in Webmin, just on the Vitualmin side in the server list. Cannot delete them.
I’ve attached the screenshot of what is recorded.
I checked in the virtual-servers folder and found files related to the servers such as:
/etc/webmin/virtual-server/domains/1394494708282642
/etc/webmin/virtual-server/saved-aliases/1394494708282642
Do you think I can delete these files?
Yes, you can just delete these files and the phantoms should be gone. 
Yup, you can indeed delete those files.
However, note that we’d recommend upgrading to the most recent Virtualmin version. It has lots of bugfixes, including a fix for the above issue, and also contains a number of big security fixes
I’m not quite sure how old version 1.675 is, that’s not in our repository, but it’s at least 5 years old.

Duh!! I gave you the version of Webmin, Vitualmin is 4.06.gpl GPL
