As pobox.com is faced with much the same situation we are
planning to develop just such a tool. There was a thread
about this a few weeks ago which we should revive when
things settle down. It could be generally useful.
Pobox customers on this list are invited to try
http://www.pobox.com/login/mason/antispam/spf.mhtml
Pobox customers have forwarding of the form
alias(_at_)pobox(_dot_)com -> address(_at_)isp(_dot_)com
If isp.com has an SPF record, the above web page will
prefill the SPF record with "include:isp.com".
if isp.com does not have an SPF record, the above web page
will prefill the SPF record with "ptr:isp.com".
