Sendmail generates a permanent failure as the sender's address doesn't resolve.

Fetchmail drops it on the floor, as per the man page (see SMTP/ESMTP
ERROR HANDLING).

I fail to see the problem.  Sendmail is doing what you've told it to -
rejecting emails with a sender domain that doesn't resolve.  Fetchmail
is doing what it's supposed to - dropping emails that the SMTP server
rejects with an error code of 553.
