Hello! A few days ago I had to restore my server from a snapshot and all went apparently well. Since my snapshot was a few days older, I downloaded my vmail folder entirely and re-wrote it to the server after the restore was completed (I thought that was a right action to do to ensure current email traffic wasn't lost) Shortly after I started having several email errors and issues. Folders content other than mailbox were not accessible, and several permission errors appeared in the log (below). I tried to fix the permissions to the folders & sub folders by changing these to 755 for one of the email accounts and that apparently helped, but I now see that all other mailboxes and accounts are also affected. Through webmail, all seems to be working OK, but when working with email clients (desktop & mobile) it is not possible to access the Mailbox folders/subfolders in a very weird way. Today I saw certificate errors in the log as well, not sure if that would be connected to my mistaken action. Would there be a way to repair these folder permissions to what these have to be? Any help and guidance on this I will really appreciate. OS version is Ubuntu 18.04.5 LTS (on a VPS) ISPConfig version is 3.2.2 php (cli) version is 7.2.24-0ubuntu Using Dovecot htfreport.txt (removed multiple iptables lines to make it readable) and mail log attached.
Run: chown -R vmail:vmail /var/vmail to cahnge the vmail folder and alls its sub folders and files to user and group vmail and then check if the issue is fixed.
