Hello Rob,
If your customer who owns "customerdomain.com" wants their domain
protected from forgery by SPF, then yes, their domain name would also
need an SPF record. They, however, could use the include mechanism in
their zone, like this:
"v=spf1 include:ourserver.com ~all"
...and after a reasonable period of time, changing the tilde (~) to a
dash (-) is in order.
You should also be aware that you might not know all the different ways
your customer sends their email. They might also send using other
systems other than your server. If that is the case, the additions to
the SPF record would be required.
