Mail Fraud on Server
About 1 hour ago I received a very suspicious subscription payment through PayPal (who signs up dkjshkjhdskjf.com and agrees to pay $17.95 a month?) - So I checked out what he has uploaded so far... sure enough it's a sendmail script with a message uploaded on the server regarding a SunTrust mail scam. First thing I do is terminate this account. About 15 minutes later I get an email from PayPal saying my payment was put on hold because the buyer's account was used without his consent. I reply to that email, releasing the funds back to the defrauded buyer.I check the server load and it's 7.99! so obviously this guy's messages are still being routed through the server. I panic and force reset through WHM. When the server comes back online I notice the server is still processing the emails, so I panic some more and shut down exim. I submitted a support ticket to theplanet notifying them of this issue - and was forwarded to their abuse group (which hasn't responded yet).
I'm kind of in limbo here -- If any of you have had similar experiences, how have you dealt with it, what did you do to investigate the damage, what CAN I do? I'm already receiving replies and abuse reports since the messages are being sent with a nobody@velocity.pixdserver.com reply address.
Thanks for you help.
