Hi !!
If the owner does not care about responsibility, why would they bother
with SPF in the first place?
it's easy, does not cost money and make your emails look more secure,
at the end if spf succed veryone must publish spf records, are you sure
all of them will care ? now anyone could run a mail server, but do all
of them care ? really not.
By publishing a record stating which hosts
are authorized to send mail on your domain's behalf, is that not
fundamentally saying that you care which hosts may send mail?
no, you are just saying that that hosts could send email using your
domain, nothing else.
And if
one of your authorized hosts is spamming, are you not accepting
responsibility for that by enabling the receiving machines to identify
that the spam did in fact come from one of your authorized hosts as
opposed to a forgery?
no, by publishing spf records you are not accepting any responsinility
about what spf-authorized computers do.
I really can't think of any plainer way to say
it; publishing SPF indicates that the entity in question does care,
otherwise they wouldn't bother.
yes, but they will, some moment in the future people will publish spf
records because veryone else does, but this does not imply that they
will care about anything.
