Adding a parameter to the content-type of an attachment using nsIMsgAttachment ?

[AJ Banck]

Hi,

I am trying to use the nsIMsgAttachment interface to add an attachment to an
email message.

Problem is that I can't find a way to set the Content-type to have
parameters, like: "Content-Type: text/calendar; method=REQUEST"

Looking at the code it seems that this is stripped.

Is this a bug, or is there a special reason to disallow setting an
attribute? any work-around for this, maybe there is another interface I
could use or hack up the message directly?



Also, is it possible to set the content type of the main message, when not
using text or html?

Code in nsMsgAttachment.cpp:
NS_IMETHODIMP nsMsgAttachment::SetContentType(const char * aContentType)
{
  mContentType = aContentType;
  /* a full content type could also contains parameters but we need to
     keep only the content type alone. Therefore we need to cleanup it.
  */
  PRInt32 offset = mContentType.FindChar(';');
  if (offset >= 0)
    mContentType.Truncate(offset);

  return NS_OK;
}
