Hi
I have setup a LB to service two Exchange 2016 servers. Thus, I have virtual services on port 80 and 443 using the Kemp MS Exchange Template In addition, on port 25 between the LB and the Exchange servers I have two spamfilter-servers that analyze the SMTP traffic using the SMTP template for the virtual service.
However, the spamfilter servers cannot see the beyond the Kemp LB and think that the LB local IP (192.168.100.100) is the spam source. Is it possible to set the SMTP template so that the Kemp LB is not acting as a proxy server and therefore, every email coming into the spamfilter appears to come from the LB and that the LB is not hiding the identity of the actual sender?
Best regards,
Kristian
