When receiving e-mail (http://code.google.com/appengine/docs/java/mail/ receiving.html), is there a way to access the envelope (SMTP-level) data for the message? In particular, the envelope sender (SMTP "FROM" parameter)?
Under some circumstances, my application needs to bounce messages back to their sender. My understanding is that the best practice is to send bounces to the envelope sender. However, this is not part of the message itself, so it's not available via the MimeMessage one extracts from the request body. Does App Engine make the SMTP envelope sender available anywhere? -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
