We have a Fortimail 100c spam appliance installed in front of our exchange server (100-200 users). I have no knowledge of how to use or configure this system but I have noticed in the main dashboard a huge amount of outgoing spam emails. Any idea how to fix this? I'm pretty sure my mail server has been now blacklisted on a lot of spam awareness sites, doesn't sound like any good can come out of that. I've attached a picture to show how much outgoing spam there is.
Thanks for the help.
