Case Creation Through Inbound Email.

I am facing following issues in my log file ;

*** FOLDERS: addBean() is trying to save to a non-saved or non-existent folder

Unable to find relationship emails_email_templates.

and finally

Job xxxxx (Check Inbound Mailboxes) failed in CRON run.

This works totally fine in my local instance but it gives these errors on live. It is not creating a case from inbound email.

Check error log
