That is good to know.  I was a bit confused by some of the options.  So if 
I have a VPS and all my users for "domain.com" are using either webmail or 
a mail client whose SMTP and POP settings are "domain.com", then this 
should work just fine:

"v=spf1 a ip4:10.10.7.1 include:domain.com ~all"

Yes?

Does specifying an IP mean that I could just use "include" to specify all 
of the domain names that I am hosting on that one machine?

Thanks,
Jonathan
