Welcome to security.SE, but this question is highly specific to a software package. Take a look at the FAQ for tips on how to pose a question appropriate to this forum. security.stackexchange.com/faq – schroeder Nov 22 '12 at 19:48
This type of question may be better suited for the related site serverfault.com .. they know how to configure server side software – makerofthings7 Nov 23 '12 at 0:11

First google response: http://www.gossamer-threads.com/lists/spf/help/29571

From my data file, edited to protect the guilty: 'example.com:v=spf1 ip4\072192.168.001.01/30 -all:3600 :example.com:99:\041v=spf1 ip4\072192.168.001.01/30 -all:3600

Starting colon says look after the domain name for the type in decimal, then, after that the \041 is a designator for a single byte in 'octal'. In the SPF (type-99) record it appears that it should be just like the 'txt' record, but prefixed with the length. Note that the \072 later on is ':', and should be counted as a single character.
