+ - userdb lookups aren't verifying / translating usernames
+ - message-header-decode.h API: Add support for returning UTF-8 decoded strings

+ - Fix Sieve plugin to decode headers using it
+
+ - maildir+pop3/deliver fast updates:
+ - with locking enabled, pop3 could just keep the one and same sync lock and
+ do the whole thing using sync transaction
+ - don't update dovecot-uidlist if dovecot.index.cache doesn't exist /
+ there's nothing to cache
+ - if all messages are expunged and there are no unknown extensions in index,
+ unlink dovecot.index and rotate log and add some initial useful info to
+ the log (uidvalidity, nextuid)
+
+ - maildir
+ - physical separator could be configurable
+ - setting flags to same as they already are causes unnecessary
+ rename()s with identical parameters
+ - deliver+maildir: if new mails are in new/ or cur/ they're not added to
+ dovecot-uidlist but newly saved mails are, so UIDs will be in wrong order
+ - maildir_copy_with_hardlinks: We're currently first hardlinking to tmp/ and
+ then rename()ing. This wouldn't be necessary if uidlist syncing noticed
+ that someone else already had added them to uidlist, and the existing UIDs
+ could be assigned to them in the index.
+ - maildir_copy_preserve_filename=yes has a race condition causing "Append with
+ UID n, but next_uid = y" errors when quota plugin is loaded. Practically
+ won't happen except in stress testing.
+ - maildir_copy_with_hardlinks=yes is problematic with shared folders where

+ - mbox
