And that's a perfectly fine idea, except when one of those partial
solutions can have undesirable side effects. In the case of SPF we've
heard of at least two so far:
1) When used without ?all, those scoring messages using SPF may end up
blocking legitimate messages from non-listed servers.
2) SPF may be used as a mechanism for DNS attacks.
