Documentation wrong for email notifications per smtp

[konsti]

Hi,

on your website you have the following in your documentation:

[...]
=== SMTP Options (when delivery_method = :smtp) ===
server_host     - The String hostname of the SMTP server (default: localhost).
server_port     - The Integer port of the SMTP server (default: 25).
server_auth     - The Boolean of whether or not to use authentication
                  (default: false).

=== SMTP Auth Options (when server_auth = true) ===
[...]

So you define server_auth as a boolean.

Looking into your code in this file:
https://github.com/mojombo/god/blob/master/lib/god/contacts/email.rb#L113

you send the server_auth argument to the smtp server:

def notify_smtp(mail)
    args = [arg(:server_host), arg(:server_port)]
    if arg(:server_auth)
      args << arg(:server_domain)
      args << arg(:server_user)
      args << arg(:server_password)
      args << arg(:server_auth)
    end

    Net::SMTP.start(*args) do |smtp|
      smtp.send_message(mail, arg(:from_email), arg(:to_email))
    end
  end

If I set server_auth to true, like defined in your documentation I get the error

INFO: failed to send email to me@example.com via smtp: wrong authentication type true

because true is not a valid authentication type for smtp.

Correct is for example

d.server_auth = 'plain'
