Maddy mail server how to specify the dkim selector? For example, I want to use my habit of 20230713 instead of default, please advise, thanks.

I'm just dipping my toe into Maddy, but I think you want to change the dkim line in maddy.conf under the submission section:

default_destination {
    modify {
        dkim $(primary_domain) $(local_domains) default
     }

Try changing 'default' to '20230713'.

Thank you, I changed it, but it didn't work, and even without changing the slector, the windows client can connect to send mail, but the PHP forum script can't connect with the same username and password, so I fell back to postfix dovecot rspamd. All problems solved.
