On a general basis, I recommend against using SPF, but if one "must" use
SPF, remember to NOT set it restrictively.
That is: never, ever use "-all" or similar constructs that restrict message
handling to a few hosts, unless you are absolutely certain that messages
will NEVER exit your private/company network.
