Your timestamps suggest you did this the other way around.
Aki mentioned that issue is/will be fixed, but DH parameters can take a *very* long time to generate if you're unlucky, so maybe it's a timing issue (using the service before the DH parameters was ready.)
I think I would ask you to ignore the timestamps in this instance. I can tell you from fact that I deleted the old .dat file, restarted dovecot, and waited for it to regenerate the file (i.e. there was nothing there, and then there was ...). So I can guarantee you that the file there at the moment very much is a new file, and that I waited for that new file before testing again.
