[Dovecot] 1.0.rc20 released

http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz http://dovecot.org/releases/dovecot-1.0.rc20.tar.gz.sig

So, rc19 was somewhat broken. How about this version?

+ dovecot: Added --log-error command line option to log an error, so
  the error log is easily found.
+ Added mail_log_max_lines_per_sec setting. Change it to avoid log
  throttling with mail_log plugin.
- Changing message flags was more or less broken in rc19
- ACL plugin still didn't work without separate control directory
- Some mbox handling fixes, including fixing an infinite loop
- Some index file handling fixes
- maildir quota: Fixed a file descriptor leak
- If auth_cache was enabled and userdb returned "user unknown"
  (typically only deliver can do that), dovecot-auth crashed.
- mail_log plugin didn't work with pop3
