Hi.
You are on a WHM/Cpanel VDS if my memory serves me right.
So As Adrian suggested with respect to the Bogus Mails you could the following at SMTP Level:
(1). Block All Messages presenting your interface address in HELO/EHLO
(2). Block All Messages presenting your localdomains in HELO/EHLO
(3). Activate the antivirus/dangerous content filter from WHM
(4). Install ClamAV and reject all infected Messages. Quit Mailscanner route if you are using one as cpanel has already stopped support for this. But be careful that since you are on a VDS (implying shared resources/limite resources), do not install the default installation from WHM as it also scans for file uploads.
(5). Block fake bounce messages, by checking a recipient count and bounce messages are not delivered to multiple recepients.
This is the minimum you could do.
