The fix is now merged to master. It ended up being a bit different (simpler) from what Jeff sent to the list. The main fixes are: https://github.com/dovecot/core/commit/4e5bb6738d8907ede8ec157d07463a8e77293ba8 <https://github.com/dovecot/core/commit/4e5bb6738d8907ede8ec157d07463a8e77293ba8> https://github.com/dovecot/core/commit/1d9b4e14008b15b7a34b5c633b09b9670e866256 <https://github.com/dovecot/core/commit/1d9b4e14008b15b7a34b5c633b09b9670e866256>
