Technical Update: 1) I've moved our email provider to AWS SES.

Microsoft (live.com.au/hotmail.com etc) was rejecting our emails over the last few days, so hopefully this issue is resolved.

2) I've moved to our media to a new storage provider called Wasabi. You shouldn't notice any difference.

@aussocialadmin HotMail will also tell you they accept email, but not actually deliver it - not even into the spam folder.
