Hello

Suddenly yesterday thousands of bounced emails hitting my server and when i checked WHM in the Mail Queue Manager I see many emails waiting to to be sent as shown on the attached image

If those emails are listed in the Mail Queue Manager does it mean its for real comming out from my server or it might be spoofing?

cpanel dedicated server
CentOS release 6.5 (Final)
whm/cpanel WHM 11.40.0 (build 26)

I was able to solve the issue by changing the email account password and made very strict rules for CSF/LFD firewall
