Oops. I guess I assume everyone uses Linux (and Debian at that.. :) I don't know how dovecot is set-up with FreeBSD. The error you showed was similar (or the same, I don't know anymore) to the one I had when I upgraded to 2.3.1 on Debian, the root cause of which was the new restriction disallowing dovecot to get new privileges (which meant it could not run postdrop as root, despite being setuid). .. but for FreeBSD, I'll have to pass.. :) Good luck!
