Hi All,

Not sure if there is anyone on list from MS, or who has contacts at MS, 
but I am trying to get this info to them.

I have been getting notifications from clients about MS 365 emails being 
quarantined due to SPF failures.

It appears that mail is coming from 2a01:111:f403:e40d::2 which is not 
matching against the spf.protection.outlook.com record.
