Message: Warning: 50 emails have just been sent

The id788161 account has just finished sending 50 emails. There could be a spammer, the account could be compromised, or just sending more emails than usual. After some processing of the /etc/virtual/usage/idXXX.bytes file, it was found that the highest sender was idXXX@mijndomein.nl, at 45 emails. The top authenticated user was idXXX, at 91 emails. This accounts for 182% of the emails. The higher the value, the more likely this is the source of the emails. An authenticated username is the user and password value used at smtp time to authenticate with exim for delivery. The most common path that the messages were sent from is /home/idXXX/domains/mijndomein.nl/public_html, at 91 emails (182%). The path value may only be of use if it's pointing to that of a User's home directory. If the path is a system path, it likely means the email was sent through smtp rather than using a script. The top sending script was /home/idXXX/domains/mijndomeinl/public_html/libraries/vendor/phpmailer/phpmailer/class.phpmailer.php:689, at 74 emails, (148%). Because the bulk of the emails have been sent by the script, please check it to confirm it has not been compromised.
