Trying to restore a backup, it fails at the “Restoring mail files” stage with the message:
Restore failed : Failed to open /home/$username/public_html/Maildir/cur : No such file or directory
CEntOS 7, Virtualmin 6.07
Is this thing abandonware?
https://www.howtoforge.com/community/threads/err-maildir-invalid-no-cur-directory.4836/ shows a similar issue and a resolution. Does it work for you?
Doesn’t seem to be the same issue. In my case Virtualmin is trying to restore a maildir as a subdirectory of the virtual server’s public_html dir instead of where it came from, killing the restore job.
