Hi, few months ago I successfully followed the tutorial "Update the ISPConfig Perfect Server from Ubuntu 20.04 to Ubuntu 22.04". Few weeks ago I used rsync to restore a block of mails still stored in an old machine (using the courier-dovecot-migrate.pl script). Everything seemed to work properly, but then a couple of days ago, I discovered in the log files these kind of messages (every few days it's happening for a different account with hundreds of mails). I suppose there was some problem with retrieving old emails. Has anyone had something like this happen to them? Is anyone able to explain what is happening and why? Thank you in advance
