With component-based solutions like Mailu, the junk/non-junk categorization you do in your mail client (via folders, not flags) indeed does inform the training of the spam filter used on incoming mail.
There are advantages to an integrated solution: The junk/nonjunk flags you set in your mail client are used to assess incoming email (based on full sender/domain/orgdomain/spf/dkim/ip/ipsubnets). I'm not sure how common/feasible that is with solutions that combine mail server components. I've used postfix & dovecot before mox, I admittedly didn't closely look into it but assumed that combo cannot do that.
