MIME-encoding of unstructured headers differs from a similar
encoding of structured headers, e.g. you can encode comments
and names in From: headers, but not the mailbox address.
For the same reason you can't encode a Subject: cmsg whatever,
and in "Subject: Re: text" you can only encode the text but
not the "Re: ".
