I'd like to extract the Final Received: email header from a message. I have the Message as returned from
Received: headers are timestamped:
Received: from lb-ex1.int.icgroup.com (localhost [127.0.0.1]) by lb-ex1.localdomain (Postfix) with ESMTP id D6BDB1E26393 for <email@example.com>; Fri, 12 Dec 2014 12:09:24 -0500 (EST)
messageInstance.get_all() and sort the resulting list however you see fit, an example of how to do this:
import email.utils import operator def sort_key(received_header): received_date = email.utils.parsedate_tz(received_header) return received_date received_header_list.sort(key=sort_key)
If it doesn't work, do leave a comment and I'll be happy to look into it further.
