Whatever the significance of the "delayed 91420 seconds", 25.4 hours was
not the time between the mail being sent and the list software sending it
out. That is closer to 11 hours (not 17.5 hours as I said previously).
As I understand greylisting, the client first has the mail rejected and
then has to try later, the default time interval for a retry generally
being 300 seconds. Perhaps mail.protection.outlook.com uses a different
IP address each time. That wouldn't go down well.
