Prevent mail from sending OUT?


In cpanel, I know there's a filter that allows you to specify something like 'if body contains THIS, then delete' - but can you do that with OUTGOING mail too?
I use CSF to filter bad traffic, and there's a scraper hounding one of my images from multiple IPs. Anytime 1 IP gets banned, he tries another.

It's filling up my inbox with these types of emails:
Abuse: [ip] ([country]/[hostname])

I still want these emails, but I don't want them if the body has the particular image file he's after. I'd like to mirror the same type of function that cpanel offers with INCOMING mail.
