SPF record passed validation test with pySPF (Python SPF library)!
Is that ":3600" part really possible? If so, what does it mean?
The :3600 part violates RFC 4408. From the ABNF:
mechanism = ( all / include / A / MX / PTR / IP4 / IP6 / exists )
all = "all"
include = "include" ":" domain-spec
A = "a" [ ":" domain-spec ] [ dual-cidr-length ]
MX = "mx" [ ":" domain-spec ] [ dual-cidr-length ]
PTR = "ptr" [ ":" domain-spec ]
IP4 = "ip4" ":" ip4-network [ ip4-cidr-length ]
IP6 = "ip6" ":" ip6-network [ ip6-cidr-length ]
exists = "exists" ":" domain-spec
