Oops, I may have misspoken. Your SPF record doesn't keep others who
send thru dyn-dns from forging your domain, but the local policies
and implementation at dyn-dns may prevent it. That is, the fact that
you have to authenticate to send thru dyn-dns allows dyn-dns to
restrict what domains you are allowed to use as your mail-from
(envelope-sender). However, I don't know if they in-fact make such
restrictions.
