fetchmail is stating that your local SMTP server (usually localhost)
rejected the sender's domain. fetchmail can't fix that.


Quite simply fix your receving end's configuration.

1. make sure your DNS works properly and can resolve legit sender domains

2. make your local SMTP server that fetchmail forwards to accept all
mail injected locally from fetchmail. Whatever software that is, you
would not mention, but likely you also need to seek its support
channels, not fetchmail's.


If you need further help, see

as to what's required to assist. Do not elide domains, we can't help you
otherwise. Replace local parts systematically.
