declaimed the following in gmane.comp.python.general:

	Technically, the server is always running -- this just connects you
(as a CLIENT) to that running server.
 
> # Send the email
> smtp.sendmail(sender, [to] + bcc, msg.as_string())

	I notice that you left OUT the CC addresses.

	Pardon --- you failed to include the ERROR, you've only supplied the
traceback identifying which line failed.

	However, presuming the error is

TypeError: can only concatenate list (not "str") to list

then the solution is obvious... DON'T try to use "+" with a string on
one side and a list on the other...

>>> [to] + [cc] + [bcc]
['ed@domain.gov', 'ed@gmailmail.com', 'ed@domain.net']

	But note that this won't work if one of the three is already a list!

>>> bcc = ["ed@domain.net", "someone.else"]
>>> [to] + [cc] + [bcc]
['ed@domain.gov', 'ed@gmailmail.com', ['ed@domain.net', 'someone.else']]

	If you ensure that each address block starts as a list, you can...

>>> to = ["ed@domain.gov"]
>>> cc = ["ed@gmailmail.com"]
>>> bcc = ["ed@domain.net", "someone.else"]
>>> add = []
>>> add.extend(to)
>>> add.extend(cc)
>>> add.extend(bcc)
>>> add
['ed@domain.gov', 'ed@gmailmail.com', 'ed@domain.net', 'someone.else']
>>>
