One of the features of Microsoft Exchange 2016 is that you can create additional folders on your Inbox in the server (server-side). Can Linux-based SMTP servers do that?
Does Exchange 2016 offer more user-friendly features or Linux-based SMTP servers?
I think you're a bit confused about what an SMTP server is. Exchange typically provides several services, one of which is SMTP. Comparing features of Exchange to similar products in the open source world is going to be difficult, because Microsoft has a vendor lock-in that makes it difficult to exactly duplicate every feature.
On Linux, an SMTP server can deliver locally to a file (such as /var/spool/mail/username) and you can read that file with several MUAs, but it sounds to me like you're asking if there is a way to have multiple folders. That's more like something provided by an IMAP server. Typically mail arrives in your mailbox via SMTP, and is then delivered into a mailbox that is read by a completely separate service that provides the IMAP protocol (or POP3, but I hope not). IMAP servers can provide you with many different 'folders' and not just an INBOX.
There are several IMAP servers for CentOS, for ease of setup I suggest dovecot. If you need a webmail client for your mail service, I suggest RoundCube (package name: roundcubemail). I prefer postfix for SMTP although there's also sendmail and exim.
