Log Message:
Update to Dovecot 1.0.6.

	* IDLE: Interval between mailbox change notifies is now 1 second,
	  because some clients keep a long-running IDLE connection and use
	  other connections to actually read the mails.
	* SORT: If Date: header is missing or broken, fallback to using
	  INTERNALDATE (as the SORT draft nowadays specifies).

	+ deliver: If message begins with a "From " line, ignore it.
	+ zlib plugin: If maildir file has a "Z" flag, open it with zlib.
	- CREATE: Don't assert-crash if trying to create namespace prefix.
	- SEARCH: Fixes to handling NOT operator with sequence ranges.
	- LDAP reconnection fixes
	- Maildir: Don't break when renaming mailboxes with '*' or '%'
	  characters and children.
	- mbox: Fixed "file size unexpectedly shrinked" error in some
	  conditions.
	- quota+mbox: Don't fail if trying to delete a directory.
