If you open the file with "r" you can't write to it.

You use bmsg for two purposes: as the iteration variable, and to get the
payload. Moreover get_payload is a method and hence needs an object.

for bmsg in mb:
        msgb = bmsg.get_payload()
        mailout.write(msgb)

But that doesn't take into account that the payload will be a list when
the message is multipart. In that case you need some more elaborate code
like:


def writebody(mailout, msg):
    payld = msg.get_payload()
    if msg.is_multipart():
        for m in payld:
            writebody(mailout, m)
    else:
        mailout.write(payld)

for bmsg in mb:
        writebody(mailout, bmsg)
        print "mailbox file copied...to SurveyResults.txt"
