[Dovecot] 1.0-test20

http://dovecot.org/test/

One more for today :) Again mostly mbox fixes and optimizations. Don't try it with maildir because it crashes with COPY and APPEND commands.

This release supports now UIDPLUS extension. It was mostly a side effect of making saving mails store the X-UID header immediately to mbox and adding the mail to index.

So, a Dovecot LDA would finally make sense now. Besides keeping indexes updated, it could also ask user's home dir, uid and gid from dovecot-auth. Now, that combined with postfix-dovecot-auth patch, Dovecot would be very simple to install with Postfix :)
