But that doesn't work anymore unless you control the DNS for all zones
in question, and can set up SPF correctly. (Mostly, that actually does
apply to me)
As a counterpoint, I have never setup SPF and generally have no
problems. I do, however, control the DNS. As a counter counterpoint,
however, not many people run their own email anymore. :-)
FWIW, I find that checking SPF is a pretty useful component of your spam
filtering strategy (if you are one of the holdouts who do still run your
own mail server). For me it bounces a couple of obvious forgeries per day
on average, which may not seem like a lot considering that the spamhaus
and spamcop blacklists bounce a couple thousand per day ... but as a
fraction of the junk that gets past my other filters, it's fairly
significant. If more people advertised SPF records for their domains,
it'd be even better.
