2. �Should I be doing something to change my config or do others feel that the vuw spf record is to wide?

From http://tools.ietf.org/html/rfc4408#section-10.1 :

�� SPF implementations MUST limit the number of mechanisms and modifiers
�� that do DNS lookups to at most 10 per SPF check, including any
�� lookups caused by the use of the "include" mechanism or the
�� "redirect" modifier.� If this number is exceeded during a check, a
�� PermError MUST be returned.� The "include", "a", "mx", "ptr", and
�� "exists" mechanisms as well as the "redirect" modifier do count
�� against this limit.� The "all", "ip4", and "ip6" mechanisms do not
�� require DNS lookups and therefore do not count against this limit.
�� The "exp" modifier does not count against this limit because the DNS
�� lookup to fetch the explanation string occurs after the SPF record
�� has been evaluated.
