I think the problem are envelope from addresses of the form '<>'. This
is not a mail address; no SMTP server will accept it. I do not know why
fetchmail constructs these addresses. Perhaps it means the special
MAILER-DAEMON address instead?

According to its man page, fetchmail will only discard mails when using
its built-in SMTP delivery and the server returns certain error codes.
So I guess you can't. But I think the real problem are the '<>'
addresses. You could try to replace them with MAILER-DAEMON.
