Newer sendmails use the SMTP From Envelope header and ignore errors-to:
(unless explicitly configured otherwise), which is the "correct" behavior, as
errors-to was a sendmailism. If sendmail was generating MIME errors, it was a
newer sendmail. :-) Note this isn't the From: header from the mail. It'll
likely show up as Return-path: in received mail.
Why couldn't you read the MIME messages?
