When a module just imports smtplib, yes.

However, in this case I think it makes sense to make the module allow 
for testing by giving it an API where you can choose how the name 
'smtplib' is resolved.

I don't see anything wrong with making allowances in the code to let it 
be tested, provided these allowances are not too intrusive.
