Over the last few days, I've seen a drastic increase in the amount of blatant spam making it inside of my organization. (Exchange 2003 behind Ironmail, Symantec Mail Security.) My security products are up-to-date and appear to be functioning correctly (aside from, of course, the additional V1agr4 messages). I have looked at the headers and don't see anything out of the ordinary. Exchange is passing mail
Is anybody experiencing this as well? If so, can you provide any insight into how the messages are getting through? Any recommendations on how to prevent?
(I'm asking on my user's behalf; my delete button works just fine, but I'm tired of the complaints...)
