When FixCRLF is enabled, the DKIM library convert bare CRs and LFs to
CRLFs during body canonicalization, anticipating that an MTA
somewhere before delivery will do that conversion anyway.

The intention is to ensure that a line ends with a CRLF on DKIM
signing as the MTA at the verification end may do that conversation
automatically, and invalidate the DKIM signature.
