Provider 'email' does not accept multiple mail addresses

[Magnati]

According to the specs email.prepare_data of notifiers the parameter to of provider email should accept a list of addresses.
It accepts the list, but does not sent mails to all addresses.

Neither is the case when doing the job of list_to_commas
providing one string with ','join() explicetely

In both cases only the first mail-address is receiving a mail

Here an example code.

import pathlib
import notifiers

def test_notify(mail_list):
    p = notifiers.get_notifier("email")

    # fill in your credentials
    my_user = "my_user"
    my_port = -1
    my_host = "my_host"

    status = p.notify(
        to=mail_list,
        username=my_user,
        message="Testmessage",
        subject="Test",
        ssl=True,
        port=my_port,
        host=my_host,
        html=True,
    )
    print(status)

if __name__ == "__main__":
    mail_list = ['my.first@foo.com', 'my.second@bar.com']
    test_notify(mail_list)
    test_notify(",".join(mail_list))

Thanks for opening this issue. I've been meaning to refactor the email provider, this is a good opportunity.
