[Dovecot] pre-1.0.rc6 / index file problems? try this

People who have had "duplicate header extension" and whatever other
random index file corruption problems, please see if this fixes
The change is also in the latest nightly snapshot (http://dovecot.org/
nightly/dovecot-latest.tar.gz). You could in general treat the latest
snapshot as "pretty much the same as the 1.0.rc16 release", so some
testing for it would be nice.
I've updated autotools that were used to build the snapshot, does
anyone have problems with compiling the snapshot? I'm going to build
the 1.0rc16 release using the same autotools.
rc16 has several changes intended to make Mac OS X's HFS+ happy. This
is mostly because currently the only computer I have is a Powerbook.
I'll get a new Linux machine in a couple of weeks hopefully.
I've still about 50 unread/possibly unanswered mails. I'll try to get
to them soon.
Here's a list of all the important changes:
* IMAP: When trying to fetch an already expunged message, Dovecot used
to just disconnect client. Now it instead replies with dummy NIL
* Priority numbers in plugin names have changed. If you're installing
from source, you should delete the existing plugin files before
installing the new ones, otherwise you'll get errors.
* Maildir: We're using rename() to move files from tmp/ to new/ now.
See http://wiki.dovecot.org/MailboxFormat/Maildir -> "Issues with
the specification" for reasoning why this is safe. This makes saving
mails faster, and also makes Dovecot usable with Mac OS X's HFS+
(after you also set dotlock_use_excl=yes, see below).
+ Added dotlock_use_excl setting. If enabled, dotlocks are created
directly using O_EXCL flag, instead of by creating a temporary file
which is hardlinked. O_EXCL is faster, but may not work with NFS.
+ If Dovecot crashes with Linux or Solaris, it'll log a
"Raw backtrace". It's worse than gdb's backtrace, but better than
+ Added maildir_copy_preserve_filename=yes setting.
+ Added a lazy-expunge plugin to allow users to unexpunge their mails.
+ maildir quota: Added ignore setting to maildir quota, which allows
ignoring quota in Trash mailbox.
+ dict quota: If dictionary doesn't yet contain the quota, calculate
it by going through all the mails in all the mailboxes.
+ login_log_format_elements: Added %a=local port and %b=remote port
- Doing a STATUS command for a selected mailbox (not a recommended
IMAP client behavior) caused Dovecot to sync the mailbox silently.
This could have lost eg. EXPUNGE events from clients, causing them
to use wrong sequence numbers.
- deliver was treating boolean settings set to "no" as if they were
"yes" (they were supposed to be commented out for "no")
- Running "dovecot" with -a or -n option while Dovecot was running
deleted all authentication sockets, which caused all the future
logins to fail.
- maildir: RENAME and DELETE didn't touch control directory if it was
different from maildir or index dir.
- We treated internal userdb lookup errors as "user unknown" errors.
In such situations this caused deliver to think the user didn't
exist and the mail get bounced.
- pam: Setting cache_key crashed
- shared maildir: dovecot-keywords file's mode wasn't taken from
- dovecotpw wasn't working with PowerPC
