I have a few mailservers to be decommissioned and in the meanwhile we’ve set up new servers using Oracle Linux 8.
We made a full backup using the helper script, transferred it to the new server and restored.
After the restore we went to admin login. Everything looked like the old server, logos, access, all the inboxes were there and the size of each mailbox matched as well.
However, using SOGo we logged in to several mailboxes and they all show empty, despite on the admin saying the emails are there.
How can I fix this and make the emails visible again? Thank you.
