I'm in the process of configuring an SMTP server in an air-gapped environment, where I also have a Zimbra mail server running on-site. What command should I use to set up the SMTP in this setup? I attempted to use the previous command, but it is checking for preflight requirements.....

Your command looks right.
During installation it will do a preflight check to see if all requirements for the backend have been met. If the preflight check fails, then you should add more resources or more disk space, depending on the reported result.

I have my running instana backend server has a air-gapped setup where I started stanctl up with pre flight check. 

While running the command it is asking for the disk requirement.

What would be the command if the server was running has a air-gapped with prefilght check skipped....

You can add the '--skip-preflight-check' option
