multiple entries for TXT record

[enigmedia]

Hi All: I have an SPF record for a domain, and I need to add an authorization
record for Godaddy as well. Is the correct syntax as follows (using shorthand
for origin):

TXT IN ("v=spf1 a mx ptr ip4:65.49.39.152/29 ~all"
"DZC=DlaVBmG")

(there is an extra space at the end of the first line, after the quote mark.)

I've checked it on a few third-party websites, and it either appears as:

"v=spf1 a mx ptr ip4:65.49.39.200/29 ~all" "DZC=DlaVBmG"

or

"v=spf1 a mx ptr ip4:65.49.39.200/29 ~all"
"DZC=DlaVBmG"

Is this the correct syntax?

TIA

This is *one* TXT record made of two strings. Whether or not the SPF
standard mandates it, it would be cleaner, IMHO, to have *two* TXT
records.

TXT IN "v=spf1 a mx ptr ip4:65.49.39.152/29 ~all"
TXT IN "DZC=DlaVBmG"

Thanks Stephane: I wasn't sure if I was "allowed" to have more than one TXT
record in a zone, and when I googled around the only references I saw were to
concatenating multiple name-value pairs into a single record.

I originally tried adding a second record, but when I did this and used some
testing websites to check the TXT records for the zone, they only returned the
first one, so I wasn't sure if having more than one was valid.

These two name-value pairs are not for the same purpose, so I will split them
into to two separate records.

I've now checked RFC 4408, the SPF standard and such a single record
would be illegal (section 3.1.3 of the RFC), since it would not be
legal SPF syntax.

Many DNS tool are buggy in that respect: they forget that several
records of the same type and name are possible (it is common for A and
AAAA records, for instance).

Thanks again for the clarification! I've emended the entry into two separate
TXT records.
