The body would have to have every line starting with white space, but
maybe it does.

The way very large headers are handled was changed. I suspect the
message *does* have a very long header line (over 8K). Some idiotic
messages that list hundreds of recipients have been seen where this is
true. In more recent Exims, the size of the entire header is limited,
instead of limiting each individual header line.
