Maybe I mis-read the question, but the question seemed to be about "my new
service".  How does the distro know anything about a user developed
service.
If the question is about postfix, the distro does the service file.

Without reading the man page, I'm going to guess the space in a command
would be backslashed.

Now I read the command line section and it doesn't seem specific on
the backslash, but I still think it will work.
They do mention if you desire all the features of a shell command line
you can get them by doing soemthing like:

           ExecStart=/bin/sh -c 'dmesg | tac'
