Yup, invalid per rfc5322 section 3.2.2:
"However, where CFWS occurs in this specification, it MUST NOT
be inserted in such a way that any line of a folded header field is
made up entirely of WSP characters and nothing else."
If the SA report is liable to include empty lines, you should not use
it unedited in constructing a header to be added. Note that the Exim
docs already warn about non-ASCII content; also problematic in
headers.

host during reception of a message.
