SPF TXT record peculiarities
|
|
Hi -
we're seeing SPF fails for various domains and wondering if it's our
verification software (apache jSPF) or the TXT record.
$ host -t txt about.com
;; Truncated, retrying in TCP mode.
about.com descriptive text "v=spf1 ip4:207.241.148.60 ip4:207.241.148.40
ip4:207.241.148.227 ip4:207.241.145.5 ip4:207.241.145.6
ip4:207.241.149.197 ip4:207.241.148.39 ip4:207.241.148.226
ip4:207.241.148.227 ip4:207.241.148.64 ip4:207.241.148.228" "
a:mclist.about.com a:ablist.about.com a:smtp.about.com a:mxc1s.about.com
a:smtpapps.about.com a:listserv1.about.com a:listserv2.about.com
a:mail.about.com a:om1.about.com -all"
...the extra ...228" " a:mclist... section looks like a mistake (perhaps
in a SPF record-generator? There are a few domains that have a similar
thing going on). I'm not familiar enough with the TXT record syntax or
the host command to actually call their TXT record "broken".
Is that malformed, or is jSPF just not parsing robustly enough? Thanks
for any insight!
