Unable to determine manager from specification: 'immediate'

[ghiewa]

do not known why?

code as,

import sys
import logging

from marrow.mailer import Message, Delivery
sys.path.append(__file__)

logging.basicConfig(level=logging.INFO)


configuration = {
        'manager': 'immediate', #'futures'
        'manager.workers': 5,
        
        'transport': 'smtp',
        'transport.host': 'smtp.gmail.com',
        'transport.tls': 'ssl', # None=='', required, optional
        'transport.port': 465, # 25, 465 = SSL
        'transport.username': '',
        'transport.password': '',
        'transport.max_messages_per_connection': 5,
        'transport.debug': False
    }


if __name__ == '__main__':
    mail = Delivery(configuration)
    mail.start()
    
    message = Message()
    message.author = [('Alice Bevan-McGregor', '[email protected]')]
    message.to = [('Your Name Here', '[email protected]')]
    message.subject = "This is a test message."
    message.plain = "Testing!"
    
    mail.send(message)
    mail.stop()

Could you re-run "python setup.py develop"?

[amcgregor]

Without feedback, and upon retrospective review, the configuration is incorrectly structured.

{
        'manager.use': 'immediate', #'futures'
        'manager.workers': 5,
}

Note the distinction of appending .use to the key name identifying which plugin to instantiate.
