According to the RFC, Net::IMAP::BodyTypeMessage should only be returned for message/rfc822, otherwise Net::IMAP::BodyTypeBasic:

RFC 3501:
  A body type of type MESSAGE and subtype RFC822 contains, immediately after the basic fields,
  the envelope structure, body structure, and size in text lines of the encapsulated message.
  A body type of type TEXT contains, immediately after the basic fields, the size of the body
  in text lines... Extension data follows the basic fields and the type-specific fields listed above
...
    body-type-1part = (body-type-basic / body-type-msg / body-type-text) [SP body-ext-1part]
    body-type-basic = media-basic SP body-fields ; MESSAGE subtype MUST NOT be "RFC822"
    body-type-msg   = media-message SP body-fields SP envelope SP body SP body-fld-lines
    body-type-text  = media-text SP body-fields SP body-fld-lines
    body-ext-1part  = body-fld-md5 [SP body-fld-dsp [SP body-fld-lang [SP body-fld-loc *(SP body-extension)]]] ; MUST NOT be returned on non-extensible "BODY" fetch
    media-basic     = ((DQUOTE ("APPLICATION" / "AUDIO" / "IMAGE" / "MESSAGE" / "VIDEO") DQUOTE) / string) SP media-subtype
    media-message   = DQUOTE "MESSAGE" DQUOTE SP DQUOTE "RFC822" DQUOTE
