Go to a RBL listing and confirm but basically you have a host or hosts sending spam from your network or a open-mail-relay. I would allow mail from only designated mail-servers and/or device. Read my HOWTO avoid being on a RBL

HINT: I would started by doing a google search for mxtoolbox and use the open-relay checker against any exposed mail-servers.

A quick remedy would be - IF you've got a second public IP - to create a secondary IP on your WAN interface to get your network connected. Of course, if there is a malware source on your LAN you'll burn this IP quickly.

Or if he has a range of subnet/address routed to him he could use a ippool and SNAT mail from a "non" BlackListed address ;)

Either way, he needs to fix the root cause to avoid being on a RBL to begin with ;)
