Hello there in Exchange forums.
I have Exchange 2010 server with all current patches and SenderID action set to reject if SPF fails. If the domain is using keyword include in their SPF TXT record (such as account.microsoft.com where for example onedrive mails come from), the sender ID fails with 550 5.7.1 Sender ID (PRA) Not Permitted, instead of accept message.
Do anyone resolve that?
