Log Message:
Update to dovecot-1.0rc3.  This release candidate should fix the following problems:

- SSL connections hanged sometimes, especially when saving messages.
- mbox: Mail bodies were saved with CR+LF linefeeds
- Mail forwarding was broken with deliver/Sieve
- dbox fixes. Might actually be usable now.
- Index file handling fixes with keywords
- Cache file was incorrectly used in some situations, which probably
  caused problems sometimes.
- Maildir++ quota: Don't count "." and ".." directory sizes \ 
to quota.
  After rewriting maildirsize file keep its fd open so that we can
  later update it. Patch by Alexander Zagrebin
