My SPF engine also returns PermError for microsoft.com, too.

Why?  Is a SPF DNS lookup Limit Other than Recursive Limits?

By the time
I got to the last of the three includes in the main record, I had
already hit 10 DNS-lookup-counted mechanisms.

Main record: 4 (1 mx, 3 includes)

The mx has three A records, so it is a 7 total here.

First include: 3 (2 a, 1 mx)

The MX is repeat of the above, so we have 6 total here.

Second include: 4 (3 a, 1 mx)

The MX has 4 A records, so thats 3+1+4 = 8

Third include: 0

Right, the grand total is 7+6+8 = 21 DNS lookups, 6 redundant lookups which
the DNS client cache will handle, if any.

Unless I got the meaning of the SPF recursive limit wrong, this should not
fail with a PermError.   This is not a recursive SPF record.  Right?
