Hi,
your DNS library is not broken. Its seems that on pobox.com
they forgot to put the record in double quotes. Thats all.
I have seen lots of these records in the wild and I always wanted
to ask if the DNS libraries should cater for these kind of
records?

Subject: [spf-discuss] TXT lookup problem
The SPF record for pobox.com is giving me trouble. It comes in two
pieces:
pobox.com text "v=spf1 mx mx:fallback-relay.%{d}
a:webmail.%{d} a:smtp.%{d} a:discards.%{d}
mx:store.discard.%{d} a:emerald.%{d} redirect=%{l1r"
"+}._at_.%{o}._spf.%{d}"
Ok, my DNS library give me a list of TXT records. I
currently go through the list looking for exactly 1 record
that begins with "v=spf1". Now it appears that I must glue
these two pieces together.
But how do I know when to stop gluing? If pobox.com also
published a record beginning with "spf2.0", then it would get
glued to the end of the v=spf1 record. Sure, I could check
for particular headers, but how could I know the complete
list? Also, I thought that the order of TXT record returned
from a query was not guarranteed?
So, is my DNS library broken? Or is the pobox.com SPF record broken?
Or am I missing something?
