Look here: http://code.google.com/p/web2py/source/browse/gluon/tools.py#327
This is inside the Mail.send method:
if not isinstance(self.settings.server, str):
raise Exception('Server address not specified')
it refers as *self.settings.server.* In Python 'self' is the convention to
refer the instance of a class
So, when having an instance of Mail class
from gluon.tools import Mail
> mail = Mail() # here we create the instance of Mail class
Now you do not have to use 'self' you have to use your instance to refer to
the instance attributes..
mail.settings.server = 'gae'
