rpm -q --scripts dovecot
preinstall scriptlet (using /bin/sh):

if [ ! -e /etc/dovecot/dovecot.conf -a -e
/usr/share/doc/packages/dovecot/example-config/dovecot.conf ] ; then
  # install default config
  echo "Did not find a /etc/dovecot/dovecot.conf. copying default
configuration"
  cp -na /usr/share/doc/packages/dovecot/example-config/* /etc/dovecot/
  # the chmod breaks the lda. lets use the more open permissions
  #chmod -Rv o= /etc/dovecot/
fi

```

so yeah ... no config if installed without docs
