Log Message:
Update to dovecot-1.orc7.  From the release announcement mail:

> Can everyone now agree that there are no more hangs? :)
>
> 	* Require that Dovecot master process's version number matches the
> 	  child process's, unless version_ignore=yes. Usually it's an
> 	  accidental installation problem if the version numbers don't match.
> 	* Maildir: Create maildirfolder file when creating new maildirs.
>
> 	+ ldap+prefetch: Use global uid/gid settings if LDAP query doesn't
> 	  return them
> 	+ %variables: Negative offsets count from the end of the string.
> 	  Patch by Johannes Berg.
> 	- kqueue ioloop code rewrite
> 	- notify=kqueue might have caused connection hangs sometimes
> 	- deliver: If message body contained a valid mbox From_ line, it
> 	  and the rest of the message was skipped.
> 	- mbox: We got into infinite loops if trying to open a 2 byte sized
> 	  file as mbox.
> 	- Don't crash with ssl_disable=yes
> 	- quota plugin caused compiling problems with some OSes
> 	- mbox: After saving a mail to a synced mbox, we lost the sync which
> 	  caused worse performance
>
> I think my v1.0 TODO list is:
>
>  - avoid duplicate flag change notifications, or in case the message is
>    also expunged don't bother notifying its flag changes at all
>    (shouldn't be hard)
>  - HFS+ avoid-hardlinks patch?
>  - 32bit -> 64bit upgrade still doesn't work without assert-crashing:
>    mail-cache-transaction.c: line 709 (mail_cache_add): assertion failed:
>    (fixed_size == (unsigned int)-1 || fixed_size == data_size)
>  - Courier-compatible INBOX. namespace gives "invalid namespace" \ 
errors

> I'm still not sure about the last one though. Could someone give me
> specific commands that clients send that causes it?

> As for the 32bit -> 64bit upgrade fix, could someone give me access to a
> x86-64 machine for a while to test it out?
