Issue with exim – Permission denied seen in logs ?

Trouble sending mails from a cPanel – server and you end up checking  /var/log/exim_mainlog and able to spot something like  this ?

Date H=( [xx.xx.xx.xx]:xxxxxF= temporarily rejected RCPT : require_files: error for /home/ Permission denied

This happens when the  permission or ownership has been altered for the given mailbox.

Fix this issue by :
