SPF disadvantages

Hello

What do you think about this statement here from the swiss providers mailing list at www.swinog.ch?

SPF is not meant to stop spam but is in fact meant to only
authenticate who the sender is.  Any domain registered just for spam
will quickly find its reputation trashed and will end up in DNSBLs
quickly.  Spammers will be forced to keep buying domains to cycle
through and then discard forever. DNSBLs will start going by the
nameservers used instead of the domains themselves, and this will
put pressure on the registrars to terminate customers who regularly
buy domains through them and then use the domains only for spam.

None of the above Good Things are possible whilst spammers can use
any domain they choose in the email addresses they use.

For a real problem with SPF, think about how this will affect people
who need to travel a lot and send email that has the domain of the
company they work for.  Also think about forwarding services where
they receive mail for foo.org and must relay it on tonthe real email
account of bar.org.  Then read the SPF literature for how they
suggest this is solved.
