How to include multiple domains in an spf TXT Record

domain-name-system spf txt-record

I am looking to setup a TXT spf record that has 2 included domains... individually:

v=spf1 include:_spf.google.com ~all

and 

v=spf1 include:otherdomain.com ~all

What is the proper way of combining them into a single item?


Solution 1:

v=spf1 include:_spf.google.com include:otherdomain.com ~all

There's no restriction against including multiple names in a single entry; Hotmail, for instance, takes this to extremes. Note that multiple includes, or nested ones, need to stay under the limit of 10 total DNS lookups for the whole SPF check.
