SMTP.connect method expects _get_socket() method to return socket object:

  self.sock = self._get_socket(host, port, self.timeout)

but overriden _get_socket() method in SMTP_SSL class doesnt' have return
statement (it sets self.sock instead).  Hence I get
SMTPServerDisconnected exception when I try to send mail over ssl.

The same seems to apply to LMTP class.

Marcin, thanks for finding the cause.  I have attached another diff
that, instead of removing the assignment, makes the _get_socket function
return the socket, which is the expected behavior.

You mentioned that the LMTP class also has this issue.  I looked through
that class, but didn't see any similar issues.  Can you please give more

Your diff is better than mine and looks quite similar to patch number 2
in #4470. If the whole #4470 can't be accepted for now, we could at
least apply this one change, because without it SMTP_SSL is totally
unusable. Daniel, maybe we can mark this bug or #4470 as critical?

LMTP seems ok indeed; I don't remember why I mentioned it. :)

Done and set this one as a dependency of 4470. It would be very good to
have a test that flexes this patch, can you work on one?

Here's a dumbed down version of the test from #4470. It requires
network, but no gmail account is needed to run the test.

Thanks, Marcin!

Same bug seems to apply to py3k, ported patches attached.

Applied to trunk in r72835, with some test fixes after (to skip the test
if SSL isn't installed).  Applied to py3k in r72836, ditto on fixes.  I
also backported the fix and test to 26-maint and 30-maint.
