Spam generated from Internal Email addresses !!!
Hi guys, wondered if anyone could help here....
We are experiancing a growing number of spam emails which appear to have come from internal email addresses..... for example..... company name is XYZ.... we're getting emails from john@xyz.com selling ******.... etc... We are running Symantec Mail security for microsoft exchange... Has anyone got any ideas or suggestions and could point me in the right direction? could this be some kind of virus on the server?

Re: Spam generated from Internal Email addresses !!!
This is very common. The spammers get a domain name then start generating a massive amount of SPAM with your domain and random names attached. There's nothing you can really do about it.

Re: Spam generated from Internal Email addresses !!!
They're spoofing the email addresses.
