	 * Activation Framework's FileTypeMap, for example the one held by this helper.

	 * needs to be a <i>fresh one on each call</i>, as JavaMail will invoke
	 * {@code getInputStream()} multiple times.
	 * <p><b>NOTE:</b> Invoke {@code addInline} <i>after</i> {@code setText};
	 * else, mail readers might not be able to resolve inline references correctly.
	 * @param contentId the content ID to use. Will end up as "Content-ID" header
	 * in the body part, surrounded by angle brackets: e.g. "myId" -> "&lt;myId&gt;".
	 * Can be referenced in HTML source via src="cid:myId" expressions.
	 * @param inputStreamSource the resource to take the content from
	 * @param contentType the content type to use for the element
	 * @throws MessagingException in case of errors
