Recently my organization has moved away from a 3rd party Edge Server and implemented Exchange 2010 Edge Servers. Mail flow is going from the HUB Server to the EDGE through Symantec's Vontu DLP product in reflect mode.
We are seeing that messages over 3 MB in size are taking, in some cases, hours or days to send. If I remove Vontu from the picture and route directly to the EDGE servers, all messages are processed and sent within seconds.
Symantec cannot figure out the issue and I was hoping that someone here may have the product in house and some insight to a configuration change needed.
Thanks,
J.
