ModuleNotFoundError.

Initial patch by Ned Jackson Lovely.

This was already done in Python3, but having it wrong leads to
incorrect debug output, so it seems worth fixing in 2.7 as well.

Patch by Victor Terrón.

This is a partial fix to the issue of servers disconnecting unexpectedly; in
this case the 421 says they are disconnecting, so we close the socket and
return the 421 in the appropriate error context.

Original patch by Mark Sapiro, updated by Kushal Das, with additional
tests by me.

Fix closes Issue11281 - smtplib.STMP gets source_address parameter, which adds the ability to bind to specific source address on a machine with multiple interfaces. Patch by Paulo Scardine.

As far as I can tell, the try/except was ancient code, from before the email
package rewrite where the philosophy of never throwing parsing errors was
adopted.

The RFC doesn't say that they are allowed; apparently many mailers accept
them, but not postfix.  Contributions to this patch were made by Felipe Cruz
and Catalin Iacob.

The changeset also adds additional indirect tests for quoteaddr (null address
and IDNA-encoded address).

Original patch by Nicolas Estibals.  My tweaks to the patch were mostly
style/cosmetic, and adding more tests.

I unfortunately introduced the regression when I refactored the code,
and there were no tests of quoting so it wasn't caught.  Now there
is one.

by the server. Many servers are buggy and advertise authentication methods they
o not support in reality. This change makes smtplib.auth() work more often in
the real world, where we face misconfigured servers and servers that advertise
methods they don't support due to the madness that is SASL.

  Re-enable all tests for windows platforms.
  Also, explicitly connect to the IPV4 address.  On windows platforms supporting AF_INET6, the SocketProxy would connect using socket.create_connection('localhost', port) which would cycle through all address families and try to connect.  It would try connecting using AF_INET6 first and this would cause a delay of up to a second.
