SPF Record Creation

I'm a bit confused on the proper syntax for our SPF record.  I have tried a couple different online tools but can't seam to get it right.  Our domain is hosted with Google Apps and we use Postini services.  We also have a few users who have hosted Exchange accounts with Intermedia.  The domain is "split" with any non-existent users (from Google) being forwarded to Intermedia.  Obviously, email gets sent from both the Google mail servers, as well as, the Intermedia servers.

Google Apps Help lists this information for creating SPF records:
1. To set your domain's SPF record, you should have access to your domain's DNS settings. On your DNS resource, publish the following TXT record: v=spf1 include:aspmx.googlemail.com ~all
2. If you choose to activate the Postini features in Google Apps Premier Edition and configure Google Apps to route email to the internet via Postini's servers, we suggest that you use this configuration: yourdomain.com. IN TXT "v=spf1 ip4:207.126.144.0/20 ip4:64.18.0.0/20 ip4:74.125.148.0/22 include:_spf.google.com ~all"

Intermedia lists this as the SPF record settings:
1. v=spf1 include:spf.intermedia.net ~all

Can anyone help me consolidate all that into the proper SPF record to include in our DNS settings?  Are you allowed to have multiple SPF records?  Maybe that would be a better way?

It basically needs to be a composite of all of those:

v=spf1 ip4:207.126.144.0/20 ip4:64.18.0.0/20 ip4:74.125.148.0/22 include:aspmx.googlemail.com include:_spf.google.com include:spf.intermedia.net ~all

It says each and every one of the individual entries are permitted to send mail as your domain name.

That should do it :)

You can just combine the two examples:
"v=spf1 ip4:207.126.144.0/20 ip4:64.18.0.0/20 ip4:74.125.148.0/22 include:_spf.google.com include:spf.intermedia.net ~all"

That appears to have done the trick.  Thanks.
