Exchange Online servers blacklisted RRS feed

Answers

  • You can open a support ticket within the portal, but its likely Microsoft is already aware of this.

    Also keep in mind, that Exchange Online has two IP pools for outbound mail. There is a normal pool and a "high risk" pool that it moves some outbound traffic into. This IP could be in that.

  • Hi

    Is the blacklist check always for the same IP or does it change? You could click on Detail and contact them yourself if its the same IP.

  • Generally with de-listings they want to deal with the owner of the server don't they?

    There's other IPs, for example 104.47.116.208 is also blacklisted and with even more spam engines.
