[Dovecot] Logs when moving mails

Hi,

I have a problem with an older mailserver. We have an account where 10 Users use one IMAP Account to manage their work. Sometimes some of the emails seem to disappear. I think they are moved somewhere but I can´t tell it for sure.

Is there a way to make dovecot logging any movement of emails (I would prefer doing it only for one account). This account is not a local user.

Thanks for your help,

Chris
