Google App Engine Mail API doesn't include headers when sending outgoing message

I'm trying to send an email with a header via GAE Mail API. I set a header:

message.setHeader("X-Priority", "1");

But AppEngine ignores it. And when I receive an email it doesn't contain a priority header.

Does anybody know how can I set the priority header for outgoing emails?

The Google App Engine Mail API only supports the specific headers listed in the documentation, currently:

  • In-Reply-To
  • List-Id
  • List-Unsubscribe
  • On-Behalf-Of
  • References
  • Resent-Date
  • Resent-From
  • Resent-To
