It all depends on what you do with the box, how the applications you run utilize the cpu (single vs multithreaded/multiprocess but also stuff like cpu cache utilization. if you profile the workload that you want to run (see if its cpu, memory or io bound for instance) will help you in figuring out what works best for you.

Have a look at mailcow if you’re new to MTA’s. Use that and a (sub)domain to figure out how to set things up. Once youre satisfied with the setup, reconfigure your domain on the new MTA. Use a mailclient with $yourformat and imap support to import your old email.
And above all, dont be discouraged by the naysayers that think its an impossible task; Its not, but it is complicated to get right bc all the parts involved ;-)
what error message are you getting?
