Hey,

My log looks sometimes like: Oct 1 09:38:01 dd44414 dovecot: lda(user)<20009><9MYzGVmHdV8pTgAA+v7NQw>: msgid=<20201001073801.628713ac0...@myserver.com>: saved mail to INBOX The deliver_log_format settings are still on default. Are somebody able to explain me this part of the log message? <20009><9MYzGVmHdV8pTgAA+v7NQw>: What want dovecot to say with this? Mit freundlichen Grüßen Yours sincerely Pascal Rudolf
