Hello,
I'm new with the Exchange and Puremessage management world, this week we started to have some spam to fill up our queue viewer in Exchanger.
Our Puremessage and Exchange seems well configured, we have recipient validation enabled on our Puremessage, we have a PTR/Reverse DNS configured as well and we are not blacklisted on MXtoolbox.
It seems like a PC is infected maybe, the sender adress displayed is "< >", I'm a bit lost we're to start searching to track down where this come from and if there is a way to search in Puremessage first seems there is no outbound anti-spam. Any help would be very grateful, thank you.
Regards,
Richard
