I realize that a non-zero exit code from qmail-smtpd doesn't necessarily mean
that the remote host is sending bare linefeeds, but when I see "status 256"
repeatedly from a particular host and then take steps to pipe messages from
that host through fixcr before qmail-smtpd, mail from that host is usually (but
not always) received successfully. I'd guess that about three quarters of the
time this works.
What's the "increasingly common situation, having nothing to do with bare
linefeeds, in which qmail-smtpd will exit nonzero"?
