Hello,
we are using "Spamhaus ZEN" RBL for our Exchange.
There are a few IP-Adresses that I want to whitelist, this should work with "Add-IPAllowListEntry -IPAddress x.x.x.x"
The Command works successfully and returns the results with "Get-IPAllowListEntry"
Settings for IPAllowListConfig are "-Enabled True" and "-ExternalMail Enabled True"
My problem is that mails are being blocked even if they are on the whitelist.
Can someone tell me why that is happening?
I tried to restart TransportService and even whole Exchange server without success.
Regards
gugaua
