is there someone who can tell me if “sender.office.com” is the rbl server from Office365?
I mean the server that can list us and will stop us from sending to Microsofts Mail-Services like hotmail, outlook.com. Im not sure if sender.office.com isnt just their portal to delist
Its not as easy to find any information about that as i thought or know from other RBL-offerings like Senderscore.
Theirs is “bl.score.senderscore.com”.
