I'm following a mailserver guide that suggests the following code.
sudo groupadd --system virtual -g 5000
sudo useradd --system virtual -u 5000 -g 5000
putting the uid and gid at 5000, does this need to be that number or can i put it under 1000?
from what i understand wont 5000 include the user 'virtual' at logon screen, even if --system is included?
