Upgrade of postfix

I was going to upgrade postfix and when it installs it asks "what type of mail setup do you have?

Gives choices such as Internet, Internet with smarthost, or no configuration. Which should I use in MIAB setup or should these updates be installed in a different manner?

Thank you for any help. I am new to MIAB and want to avoid breaking the system.

Thanks,

James

I believe the “no configuration” means it will keep whatever you’re already using. I think I read this when I had a package update available. It was buried in the on-screen instructions. Hopefully someone can confirm this.

As well explained in the screen ‘no configuration’ means keeping current settings.
