I know.. we've already had this discussion to some extent.

One the one hand we have RFC2633 that is a bit vague when it comes to
the concrete canonicalization steps: "The exact details of
canonicalization depend on the actual MIME type and subtype of an
entity, and are not described here." But at least it describes basic
CRLF canonicalization.

On the other hand we have some real world MUAs that support S/MIME.. I
know for sure that Outlook does not even perform basic CRLF
canonicalization. Neither Outlook nor Thunderbird decode transfer
encodings before verifying (nor should they if I understand

So in order to support explicit S/MIME signatures Mime4j must not
automatically decode transfer encodings the way it does now. This
process is never reversible, especially for quoted-printable.

CRLF canonicalization does not worry me because it can always be
applied with a simple filter stream..

Has already been closed by Oleg.
