I have exchanger server (2019) on premise with antispam set up and IPBlockListProvider setup with famous RBL List.
I wanted to passthrough some domain on my antispam like all senders from domain "testemails.com"
Even if I create a rule in Exchange with SCL "by pass" or set to "-1" for "testemails.com", if this IP of the server is listed on a list, this mail is blocked and rejected.
How to by pass a domain or a specific mail address from the "ipblocklistprovider" ?
