When checking the email trace option in cpanel, it reported an invalid date error. We got the following log from our cpanel error log file about what is causing the issue. What do I do when cpanel email trace not working, how can I fix it look no further we have the problem solved for you.
Once you have logged in as ROOT you can now copy and paste this line in
mysql eximstats < /usr/local/cpanel/etc/eximstats_db.sql
now close out putty and the the email trace feature will be up and running.
