The ones I tried at the time couldn't. They need to take the first part
verbatim and convert it to "canonical form". Those I saw would not allow
this and end up decoding and reencoding which would break the signature.

The smime app isn't currently a full blown S/MIME client just a friendly
wrapper round the S/MIME API.
A full blown application would have a key and certificate database and
store things like the algorithms supported by each recipient so it
doesn't send mail encrypted with algorithms the recipient doesn't
support.
