So, thanks for the new patch. I tested it with my ISP's server and it works fine!

Two remaining issues though:
- in the SMTP_SSL constructor, you must add the "context" argument at the end of the argument list (after "timeout"), otherwise someone passing "timeout" as a positional argument will find their code breaking
- in the doc, you need a "versionchanged" tag for the "context" argument (in both instances)

Thank you again.
