The dovecot config is still pretty much in 1.x style; one flat file called dovecot.conf. I can easily switch to a dovecot.conf with the "!include" lines and rename my flat config file to local.conf. I've tested that and it works fine. I could also try to move all lines in local.conf to the different XX-.conf files in the conf.d subdir. What is wise and best practice? Should one edit the files in conf.d? Or will the files in conf.d be overwritten on an update of dovecot? Then I'll better stick to the way of working with the dovecot.conf with the !includes and local.conf and assume that all files in conf.d are default settings.
I think you will hear from proponents of both styles. I would say use whatever works best for you.
I personally use one dovecot.conf without any includes because I like having all my configs in one place. Less editing mutiple files, and less forgetting some configuration squirreled away in some conf.d file.
