POPython: how to store a draft email with BCC recipients to Exchange Server via IMAP?
text
Body
copied!<p>I try to store a draft e-mail via IMAP to a folder running on MS Exchange. Everything ok, except that Bcc recipients don't get shown in the draft message stored on the server. Bcc recipients also don't receive the email if I send it with MS Outlook. If I read the message back with Python after I have stored it on the server, I can see the Bcc in the draft.</p> <p>The following Python code reproduces this behavior:</p> <pre><code>import imaplib import time from email.MIMEMultipart import MIMEMultipart from email.MIMEText import MIMEText message = MIMEMultipart() message['Subject'] = 'Test Draft' message['From'] = 'test@test.net' message['to'] = 'test@test.com' message['cc'] = 'testcc@test.com' message['bcc'] = 'testbcc@test.com' message.attach(MIMEText('This is a test.\n')) server= imaplib.IMAP4('the.ser.ver.ip') server.login('test', 'test') server.append("Drafts" ,'\Draft' ,imaplib.Time2Internaldate(time.time()) ,str(message)) server.logout() </code></pre> <p>If I run this code, a draft gets stored into the <code>Draft</code> folder on the Exchange Server. But if I look at the draft with MS Outlook, it does not include the <code>bcc</code> recipient (<code>message['bcc'] = 'testbcc@test.com'</code>). <code>Message</code>, <code>to</code>, <code>from</code>, <code>cc</code> ok, no error.</p> <p>If I download drafts that already include a bcc from an Exchange folder, I can also see the bcc. Only uploading doesn't work for me.</p> <p>Any help very much appreciated. Thanks. BTW, MAPI is not an option.</p> <p><strong>Update</strong>: Thanks. <code>X-Receiver</code> didn't work for me. As for playing around with an IMAP-Folder in Outlook, I got an interesting result. If I access the draft via the IMAP-Folder in Outlook, I see the bcc. But if I access it via the MAPI-Folder, I don't see it. Will play a little bit around with that.</p> <p><strong>Conclusion</strong>: thanks for the input. Actually, the code works just fine. See below for the answer that I found.</p>
