I've been repeatedly told that SPF is no good if you use mailing lists
or if you want to forward your mail from one account to another. It is
only viable if you directly mail someone else and they respond directly
back to you, or if you control any forwarders in the delivery chain.
For another solution that is more complex, but allows forwarding/relaying,
see http://www.openspf.org/SRS and http://www.infradead.org/rpr.html
I've been using this for a few years now (thanks David!) and while I
still do get spam, the number is really minor.
