Oh, are you saying that the difference isn't just the Dovecot version, but that they are completely different systems with (somewhat) different settings also? That's much more likely the problem than the version number.

Normal enough. It's then using the Dovecot's defaults which are "dovecot" and "dovenull".

Look at this output in your 2.0.13 setup and in 2.0.17 setup and see what the differences are.
