As someone else pointed out, it can be a problem if the receiving end
implements greylisting. It may also be a problem if mail from the
domain doesn't always go through the outbound servers that do the
tagging. You might also run into problems if the receiving end does
any validation based on the envelope sender.

If your mail server is overwhelmed by bounces, BATV can help to
reduce the load as, unlike SPF, it doesn't rely on the other end
implementing the technology.
