Basically means that autoconversion features like the one in the Sendmail
MTA shall no longer be used in order to limit the risk of altering DKIM

Remember, on a similar side, the Sendmail MTA also alters the To/Cc headers
in some situations and this breaks strict header signing, if verification is
done after.
