OK... so the protocol then would be that courier should hang because
it accepted a mail from a broken client, or the alternative is that
courier having accepted the message should now go into backscatter
mode.

Any other solution is to suggest that courier should accomodate other
mta's inability to handle such messages from broken clients, which
they wouldn't have been able to handle in the first place.

Of course, I'm making the assumption that courier is relaying exactly
what it recieves and that the problem originates at a buggy client.
