Bruno, I talked to someone who explained to me how what you said
gives a way around my difficulty. Please ignore the other reply.
I'll do what you said. Thank you; I appreciate your help.

Are you opening SMTP and POP3 sockets??

If you are not developing that layer itself, just use Django's built-
in mock system. Here's my favorite assertion for it:

def assert_mail(self, funk):
from django.core import mail
previous_mails = len(mail.outbox)
mails = mail.outbox[ previous_mails : ]
assert [] != mails, 'the called block should produce emails'
if len(mails) == 1: return mails[0]
return mails

You call it a little bit like this:

missive = self.assert_mail( lambda:
mark_order_as_shipped(order) )

Then you can use assert_contains on the missive.body, to see what mail
got generated. That's what you are actually developing, so your tests
should skip any irrelevant layers, and only test the layers where you
yourself might add bugs.
