MESSAGE/RFC822 and Base64

[Zbierski Christophe]

Hello, according to RFC 2045, it is not possible to have an attachment of type message/rfc822 encoded in base64.

5.2.1.  RFC822 Subtype
   No encoding other than "7bit", "8bit", or "binary" is permitted for
   the body of a "message/rfc822" entity.  The message header fields are
   always US-ASCII in any case, and data within the body can still be
   encoded, in which case the Content-Transfer-Encoding header field in
   the encapsulated message will reflect this.  Non-US-ASCII text in the
   headers of an encapsulated message can be specified using the
   mechanisms described in RFC 2047.


But, sometimes attachments are Base64. In this case, cyrus considers that the base64 is the header of email (which is attached).
So, some commands such as:
A1 FETCH 1 BODY[2.HEADER.FIELDS TO] can take a long time and cpu (in case of the attachment is large).

Is it possible to change cyrus consider this particular case.
