Thanks for that… but would you happen to know what range of IPs that the cloud version of Discourse may be using? That would definitely help.

For instance, I received an email, headers indicating: [mx-out-04b.sjc1.discourse.org](http://mx-out-04b.sjc1.discourse.org) (64.71.168.241). Is that it, or is there a block of redundant mailservers that Discourse uses that we can make sure make it on our whitelists?
