New MacBook air

Hi,
I just got a new mackbook air and I’m traveling. I brought a backup drive with me and installed everything from my Mac mini as soon as I arrived. Since the back up drive installed everything, do I need to do anything different other than straightening out what I have done wrong previously? When I go into mail and click on message, Train as good or spam is not there, so I must need to do something different. Do I need to uninstall spam sieve and reinstall and set it up again?
Thank you, Cathy

The SpamSieve menu commands are now in the SpamSieve menu bar icon and in the Dock menu:

There’s more information about the changes for macOS Sonoma here.
