Andreas Veithen commented on AXIOM-467:
---------------------------------------
That's not what I would call a real world example. It's a specially crafted to
trigger the issue. In fact, Axiom <= 1.2.12 rejects messages that use CR
instead of CRLF in the MIME headers. To trigger a backward incompatibility
issue, the message therefore needs to use CRLF in the headers and CR in the
content. It's not impossible that there are real world systems that would
produce such (non conforming) messages, but I think it's very unlikely, in
particular considering that using quoted-printable encoding in SwA or MTOM
messages is already very rare.
