I think I'm using a version packaged for RHEL (2.12.0-10.el7), so it's
probably old, but other than that, I don't think I've done anything that
should change code paths.

I don't see check_header in the logs.
What should I set it to?

And if they don't, what's suggested?
Is there a way to configure the system to reject messages with bad
headers, but to do the rejection with a temporary, rather than a
permanent code, so that the the remote system should attempt the sending
again later?
