It also rejects email from a sender whose SPF record tells
it to - that is a problem when mail is forwarded by a mailing
list because it no longer appears to come from a "valid" address
for the sender so services like gmail which believe SPF records
with a "hard reject" flag will reject the email, causing us to
see a bounce.

So the real problem is subscribers to the list using services
like yahoo mail which ignore the reality of how email works and
think they can specify exactly where yahoo.com email should
appear to come form.
