val extract_body : ?content_type:Mimetype.t -> t -> string option

extract_body ?content_type t returns the body associated with the email part that matches the content_type mimetype, or none if t does not contain a body or part of type content_type.

val extract_body_ext' : 
  accept:
    ((Mimetype.t * (string * string option) list) option -> 'format option) ->
  t ->
  ('format * string) Core.Sequence.t

extract_body_ext and extract_body_ext' Attempt to find the message body in the preferred format.

accept is used to select only content parts in a format that is supported. If a multipart component is accepted by accept, we do NOT recursively extract the body. We do so otherwise.

order will be used to select the least part (by default the first part)

val extract_body_ext : 
  accept:
    ((Mimetype.t * (string * string option) list) option -> 'format option) ->
  ?order:('format -> 'format -> int) ->
  t ->
  ('format * string) option

val all_related_parts : t -> (attachment_name * Content.t) list

Related parts are those that are included in a multi-part message with a "Content-ID" header. This content can be referenced by adding the "cid:" prefix and stripping the enclosing '<' and '>'.

For example (from https://tools.ietf.org/html/rfc2392):

  From: foo1@bar.net
  To: foo2@bar.net
  Subject: A simple example
  Mime-Version: 1.0
  Content-Type: multipart/related; boundary="boundary-example-1"; type=Text/HTML
  --boundary-example 1
  Content-Type: Text/HTML; charset=US-ASCII

  to the other body part, for example through a statement such as:
  <IMG SRC="cid:foo4*foo1@bar.net" ALT="IETF logo">

  --boundary-example-1

  Content-ID: <foo4*foo1@bar.net>
  Content-Type: IMAGE/GIF
  Content-Transfer-Encoding: BASE64

  R0lGODlhGAGgAPEAAP/////ZRaCgoAAAACH+PUNvcHlyaWdodCAoQykgMTk5
  NSBJRVRGLiBVbmF1dGhvcml6ZWQgZHVwbGljYXRpb24gcHJvaGliaXRlZC4A
  etc...

  --boundary-example-1--

Calling all_related_parts on this email would return a list of length one where the attachment_name is "foo4*foo1@bar.net" for the single entry.

Related parts are often used for inline images.
