empty out eximstats:
First check the size of your eximstats database:
du -s -h /var/lib/mysql/eximstats
If you want to clean it then connect to mysql as root:
* mysql * should drop you in, 
if not * mysql -u root -p *
you'll be prompted for the pw.  If the root doesn't work, check /root/.my.cnf,
should have the pw saved in plain text.
then, once you're connected, run these:
use eximstats; *
delete from sends; *
delete from smtp; *

#   Direct modifications to the Apache configuration file may be lost upon
#   subsequent regeneration of the       #
#   configuration file. To have modifications retained, all modifications must
#   be checked into the              #
#   configuration system by running:
#   #
#       /usr/local/cpanel/bin/apache_conf_distiller --update
#       #
#   To see if your changes will be conserved, regenerate the Apache
#   configuration file by running:              #
#       /usr/local/cpanel/bin/build_apache_conf
#       #
#   and check the configuration file for your alterations. If your changes
#   have been ignored, then they will    #
#   need to be added directly to their respective template files.
#   #
#                                                                                                               #
#   This configuration file was built from the following templates:

#  Templates with the '.local' extension will be preferred over templates with
#  the '.default' extension.        #
#  The only template updated by the apache_conf_distiller is main.default.
