This alert means that you have a delivery problem due to a misconfigured SPF record. Tthere are one (1) or more tags after the "all" indicator in your SPF record. All of those tags that fall after the "all" tag are currently being ignored by mail servers. For example, if you have a record such as:
v=spf1 ip4:1.2.3.4 ip4: 1.2.3.7 include:spf.example.com ~ all include:spf2.microsoft.com
The include: spf2.microsoft.com will be IGNORED because it falls after the "all" tag. Therefore, per RFC 7208 Section 5.1, be sure to insert all desired tags before the ~all stipulation or the ensuing text will be disregarded.
