The last attempt to update cPanel & WHM was blocked

When you login into WHM and you see the message “The last attempt to update cPanel & WHM was blocked” most of the times at the top portion.

=========
fatal: Upgrades past 11.30 are blocked because your exim is older than 4.70 and eximup is disabled.
=========

This because cPanel is set to update itself on time basis, but eximup is disabled among the settings. You can correct it in option “update preferences” through WHM itself.
