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
