Yeah, but every once in a while you'll come across a mail server hosted at
Billy Bob's Bait, Tackle, and E-mail, or Klooful Joe's Bargain Hosting,
that doesn't understand that bounces go to the RFC821 MAIL FROM and instead
insist on sending to the RFC822 From:.

In this case, it appears to be an end user with a badly misconfigured
Fetchmail 6.3.21 that isn't handling bounces sanely.
