smtplib TimeoutError not catch

[Joaquin Alzola]

Hi Guys

Try to connect to the smtp via smtplib.

The connection is down because the Firewall has not been open yet so the exception is something that should appear.
Now I want to catch this timeout in case error happens in future.

Here the exception trace.

[2016-10-12 14:14:06,289] ERROR in app: Exception on /api/barredMSISDN [POST]

How to catch such exception? ... have been trying with a lot of combinations (of course except the correct one :))

        try:
                server.sendmail(sender, receivers, msg.as_string())
        except Exception as e: <-- have try with many combinations here
                print("SMTP could not be contacted: %s",e)
                pass
        finally:
               server.quit()
