That's the whole problem; when it breaks, you don't find out about it --
instead, the bounces go to the original message sender, or (more often)
an address which fetchmail picked out of the message headers somewhere
and decided to use as the envelope sender. It's particularly noxious
with list mail, as the bounces don't go to the list manager, and the
offending address is never removed from the list. I've got a couple of
dozen mailservers blocked at my SMTP port specifically because there's a
broken fetchmail config there, and I've been unable to reach the people
responsible.
Re-delivery by SMTP injection is a fundamentally broken design.
