Stefano Bagnara commented on JSPF-72:
-------------------------------------
Confirmed as a bug. Here is the relevant specification we are not supporting:
--------------
3.1.3. Multiple Strings in a Single DNS record
As defined in [RFC1035] sections 3.3.14 and 3.3, a single text DNS
record (either TXT or SPF RR types) can be composed of more than one
string. If a published record contains multiple strings, then the
record MUST be treated as if those strings are concatenated together
without adding spaces. For example:
IN TXT "v=spf1 .... first" "second string..."
MUST be treated as equivalent to
IN TXT "v=spf1 .... firstsecond string..."
SPF or TXT records containing multiple strings are useful in
constructing records that would exceed the 255-byte maximum length of
a string within a single TXT or SPF RR record.

> Key: JSPF-72
> URL: https://issues.apache.org/jira/browse/JSPF-72
> Project: JAMES jSPF
> Issue Type: Bug
> Components: Parser
> Affects Versions: 0.9.6, 0.9.7
> Reporter: Robert Burrell Donkin
> Fix For: 0.9.7
>
>
> We are getting parsing errors from jSPF for TXT records like:
> $ 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 error jSPF reports when checking messages with that domain is:
> Term [ip4:207.241.148.228"] is not syntactically valid: ...<monster
> regex follows>
> ...the SPF TXT record is valid, to my knowledge. So it seems like a
> parsing error that can't handle TXT records with multiple quoted terms
> on the line?
> It has been suggested that there may be firewall issues since the DNS
> falls back to TCP. I don't think that's happening, but either way... a
> bug, no?
