It is the *receivers* that set up forwarding arrangements, therefore

can do many things, including making sure the *particular* forwarder
they use does SRS (or equivalent), are whitelisted via the SPF "local
policy" option, or listed on the T-FWL.
Once upon a time, I was extremely worried about this forwarding issue.
I thought it might be a killer for SPF. I was *so* worried, that last
fall, long before most people had even heard of SPF, I created the
trusted-forwarder.org global whitelist (T-FWL) to help deal with this
situation. I expected to be flooded with forwarders that needed to be
whitelisted, but it simply has turned out not to be the case in
practice. It appears that the amount of forwarded email on the modern
internet is extremely small.
I disagree with that analysis. IMHO, the lack of major problems with
forwarders to date has more to do with the lack of recipients who do SPF
checks. Forwarding is extremely common and will probably stay that way for
the foreseeable future. The reason is simple: people change email
providers like they change cell phone companies and they want keep their
email addresses. You don't, I don't, and neither does anyone else who owns
their own domain, but a lot of individual email users depend on this. Ask
Meng. Ask IEEE.org. Ask the alumni departments of most universities.
About half of the users on my own little domain have set up forwards to
places that they prefer to pick up their email from.
Perhaps in other countries, regions, cultures this is different, but the
people that I know do not change their email address if the do not have
to. They change the email when they change employment, but private email
addresses normaly are free email providers (hotmail, GMX or a local
provider). And if something is free and works ok, why change?
It is *because* I'm so involved with the SPF forwarding situation and
*because* I have actual data about how often the T-FWL is used, that I
have changed my mind. In practice, forwarding is a very small problem.
At present, that may well be true as far as SPF is concerned. But as more
recipients start to do SPF checks, I believe things will appear quite
different. At that point, I think you will be glad you had the foresight to
start trustedforwarders.org and include the whitelisting features in the
library.
Even if I do not use trusted forwarders.org (yet?), I agree with Seth,
trusted forwareders.org is a good idea.
