Issue after migration

maverick

Hi all,

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.

Ok so with the help of amazing foxcris on the IRC channel directed me straight to the issue;

On mailcow.conf the new config has the variable MAILDIR_SUB=Maildir whilst the old config this variable is empty. I disregarded this change on the first look but it was the exact issue. Putting it empty solved it.
