Hello, Aki created this patch a while ago: http://files1.directadmin.com/services/custombuild/patches/maildirlock-crash.patch It works perfectly to fix the issue :) Regarding dsync - I don't think it's a good replacement in all the cases, is it? We use maildirlock extensively for compression of email folders (when zlib compression is enabled in dovecot, old emails remain untouched). -- Best regards, Martynas Bendorius> On 2019-12-07, at 00:46, Stephan Bosch via dovecot <dovecot at dovecot.org> wrote: > > > > On 22/10/2019 05:44, lty--- via dovecot wrote: >> Dear all, >> Dovecot upgraded from v2.2.36 to v2.3.8 There is no problem with the configuration, but the lock directory seems to have an error. >> >> [root at spam dovecot]# /usr/libexec/dovecot/maildirlock /path/to/maildir 1 >> Panic: BUG: No IOs or timeouts set.

Has anyone found a good walkthrough/guide on setting this up and also on compressing the old mail? Are there any common issues to watch out for? Is it entirely transparent to the user? https://wiki2.dovecot.org/Plugins/Zlib says it has moved to https://doc.dovecot.org/plugin-settings/zlib_plugin/ which does not exist. "Not Found The requested URL /plugin-settings/zlib_plugin/ was not found on this server." -- I'm dangerous when I know what I'm doing.
