Hi , our public UP is being blacklisted by CBL.
Reason given: This IP is infected (or NATting for a computer that is infected) with an botnet that is emitting email spam. The infection is probably sendsafe.
I'm assuming that one o the 25 or so computers in my network is infected.
Question: Is there a way usnijg the Sonicwall to determine in a machine is acting as an SMTP server and sending out spam email?
My SonicWall is a new model NSA 2600 with updated SonicOC
