    I fully agree on reducing SPF records to reduce DNS lookups as they are limited to 10 according to RFC7208.

    The include:spf.protection.outlook.com parameters needs 3 DNS lookups which could easily be reduced to 1 if Microsoft Office 365 admins configure a:submission.protection.outlook.com and put al necessary IP address in this domain like a round-robin configuration.

    This also reduces DNS traffic for all parties.
