I have set up SPF records for an inactive domain, game4grrls.com,

AARGHHHHH. Yes. It is games4grrls.com (plural). Need more coffee....
That all looks OK, with the possible exception of the TXT records for
spf-exp.nomail.metron.com, of which there are two. I notice that one of
these ends in a space, so perhaps you're expecting them to be
concatenated? The TXT records are returned by the resolver in a random
order, so there's no guarantee which one will be first.
;; QUESTION SECTION:
;metron.com. IN TXT
;; ANSWER SECTION:
metron.com. 7200 IN TXT "v=spf1 a mx
a:spinach.metron.com a:violet.metron.com a:indigo.metron.com
a:pop.metron.com ip4:192.160.193.0/24 ip4:207.251.147.0/24 ?all"
That one looks OK but could be optimized a bit by moving the the ip4
parts to the start of the record, which would reduce the number of DNS
lookups required for connections from IPs in those ranges.
done. Thanks again.
You still have the bare "a" and "mx" entries first; I'd move the ip4
entries in front of those too.
Cheers, Paul.
