Greetings,
So now, what I have going on is a mm virus on the intranet? Virus for sure. Server is Exchange 2003. Clients use Outlook 2003.  We are receiving e-mails from spoofed addresses on our intranet i.e. evu@snoopy.com and not gjones@snoopy.com.  I can identify the IP address where they are coming from, but am unable to block the IP address or the sender.  I use SMSSMTP v4.1.15.47 which is catching most of the e-mails that try to come in, but not all, obviously.  I have not been able to identify the virus, but so know that the spammed e-mails are not getting out of our network - yet. Any suggestions?
