My network keeps getting spam from people trying to sell me stocks. The
messages usually have somne sort of image in them which contains the ses
pitch and its then followed by a lot of meaningless text, each message comes
from a different sender and there doesn't seem to be any other commn factors
except what I described. I now just put every sender in my outlook's blocked
senders list but its a loosing battle. I wonder if its possible to make up a
rule that blocks this spam at the ISA server?
