Anyway, I'm running into this problem a lot lately

admin problems - seem to outweigh the "pros" so far.
It breaks lots of things - e.g. mail forwarding, maybe some mailing list implementations,
but there is a feature in SPF which I really like (and use). If a domain should not be
used for sending email at all, you can publish that in SPF with "v=spf1 -all".
I check for this and can filter a few hundred mails a day sometimes.. anything that I can
match on before running spamassassin is a great thing for resource preservation !
This sometimes comes up on the mailop.org
